Question

What is 5x+10=2x-5=180

Answer 1

Answer: 34
5 times 34=170
170+10=180

Answer 2

Answer: $x=-5$

Move all terms to the left

$5x+10-(2x-5)=0$

Get rid of parentheses

$5x-2x+5+10=0$

Add all the numbers together, and all the variables

$3x+15=0$

Move all terms containing x to the left, all other terms to the right

$3x=-15\\x=-15/3\\x=-5$
