Question

solve for x
5(x-10)=30-15x

Answer 1

Answer:

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

Step-by-step explanation:

Answer 2

Answer:

$x=4$

Step-by-step 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!
