Answer 2

Answer:

$\displaystyle x=1$

Step-by-step explanation:

First, add by 5 from both sides of equation.

$\displaystyle7x-5+5=2x+5$

Simplify.

$\displaystyle7x=2x+5$

Then, subtract by 2x from both sides of equation.

$\displaystyle 7x-2x=2x+5-2x$

Simplify.

$\displaystyle 5x=5$

Divide by 5 from both sides of equation.

$\displaystyle\frac{5x}{5}=\frac{5}{5}$

Simplify, to find the answer.

$\displaystyle 5\div5=1$

x=1 is the correct answer.
