Question

10x+8 = 11x -8

Solve for x.

Answer 1

Answer:

x = 16

Step-by-step explanation:

We are given the equation:

$\displaystyle \large{10x + 8 = 11x - 8}$

First, subtract both sides by 10x.

$\displaystyle \large{10x - 10x+ 8 = 11x - 10x - 8} \\ \displaystyle \large{8= x- 8}$

Then add both sides by 8 to isolate x-term.

$\displaystyle \large{8 + 8= x- 8 + 8} \\ \displaystyle \large{16 = x}$

And we're done! The value of x is 16.
