## Step by Step Solution ### Rearrange:

Rearrange the equation by subtracting what is to lớn the right of the equal sign from both sides of the equation : 4/5*x-3/4*x-(3/10*x-1)=0

## Step 1 :

3 Simplify —— 10Equation at the end of step 1 : 4 3 3 ((—•x)-(—•x))-((——•x)-1) = 0 5 4 10

## Step 2 :

Rewriting the whole as an Equivalent Fraction :2.1Subtracting a whole from a fraction Rewrite the whole as a fraction using 10 as the denominator :

1 1 • 10 1 = — = —————— 1 10 Equivalent fraction : The fraction thus generated looks different but has the same value as the whole Common denominator : The equivalent fraction and the other fraction involved in the calculation mô tả the same denominator

Adding fractions that have a common denominator :2.2 Adding up the two equivalent fractions địa chỉ cửa hàng the two equivalent fractions which now have a common denominatorCombine the numerators together, put the sum or difference over the common denominator then reduce khổng lồ lowest terms if possible:

3x - (10) 3x - 10 ————————— = ——————— 10 10 Equation at the over of step 2 : 4 3 (3x-10) ((—•x)-(—•x))-——————— = 0 5 4 10

## Step 3 :

3 Simplify — 4Equation at the kết thúc of step 3 : 4 3 (3x - 10) ((— • x) - (— • x)) - ————————— = 0 5 4 10

## Step 4 :

4 Simplify — 5Equation at the over of step 4 : 4 3x (3x - 10) ((— • x) - ——) - ————————— = 0 5 4 10

## Step 5 :

Calculating the Least Common Multiple :5.1 Find the Least Common Multiple The left denominator is : 5 The right denominator is : 4

Making Equivalent Fractions :

5.3 Rewrite the two fractions into equivalent fractionsTwo fractions are called equivalent if they have the same numeric value. For example : 1/2 và 2/4 are equivalent, y/(y+1)2 và (y2+y)/(y+1)3 are equivalent as well. Khổng lồ calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.

x - ((3x-10) • 2) đôi mươi - 5x ————————————————— = ——————— trăng tròn 20

## Step 7 :

Pulling out lượt thích terms :7.1 Pull out lượt thích factors:20 - 5x=-5•(x - 4)

Equation at the over of step 7 : -5 • (x - 4) ———————————— = 0 đôi mươi

## Step 8 :

When a fraction equals zero :8.1 When a fraction equals zero ...Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.Here"s how:

-5•(x-4) ———————— • trăng tròn = 0 • 20 20 Now, on the left hand side, the đôi mươi cancels out the denominator, while, on the right hand side, zero times anything is still zero.The equation now takes the shape:-5 • (x-4)=0

Equations which are never true:8.2Solve:-5=0This equation has no solution. A a non-zero constant never equals zero.

Solving a Single Variable Equation:8.3Solve:x-4 = 0Add 4 khổng lồ both sides of the equation:x = 4
