5(x-10)=30-15x

Answer 1

solution :

x = 4

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

5*(x-10)-(30-15*x)=0

Step by step solution :

Step 1 :

Equation at the end of step 1 :

5 • (x - 10) - (30 - 15x) = 0

Step 2 :

Step 3 :

Pulling out like terms :

3.1 Pull out like factors :

20x - 80 = 20 • (x - 4)

Equation at the end of step 3 :

20 • (x - 4) = 0

Step 4 :

Equations which are never true :

4.1 Solve : 20 = 0

Explanation:

Answer 2

`x=4`

Explanation:

`5(x-10)=30-15x\\5x-50=30-15x\\5x-50+50=30-15x+50\\5x=-15x+80\\5x+15x=-15x+80+15x\\20x=80\\\cfrac{20x}{20}=\cfrac{80}{20}\\x=4`

Hope it helps!
