5 (bx-2ab) = b (x-7a) + 5ab solving for x

x = 2a

Step-by-step explanation:

5 (bx-2ab) = b (x-7a) + 5ab

5bx - 10ab = bx - 7ab + 5ab

4bx = 8ab

x = 8ab / (4b)

x = 2a

x = 2a

Step-by-step explanation:

5 (bx-2ab) = b (x-7a) + 5ab

Distribute

5bx - 10ab = bx - 7ab + 5ab

Combine like terms

5bx - 10ab = bx - 2ab

Add 10 ab to each side

5bx - 10ab+10ab = bx - 2ab+10ab

5bx = bx+8ab

Subtract bx from each side

5bx - bx = bx - bx + 8ab

4bx = 8ab

Divide each side by 4b

4bx/4b = 8ab/4b

x = 2a
