Answer:
X = 15
Step-by-step explanation:
We move all terms to the left:
<em>x+8+2x-(2x+13)=0</em>
We add all the numbers together, and all the variables:
<em>3x-(2x+13)+8=0</em>
We get rid of parentheses:
<em>3x-2x-13+8=0</em>
We add all the numbers together, and all the variables:
<em>x-5=0</em>
We move all terms containing x to the left, all other terms to the right:
<em>x=5</em>

Answer:
x = 2y − 2
Step-by-step explanation:
x + y + 5 = 2x - y + 7
−x + y + 5 = −y + 7
−x + 5 = −2y +7
−x = −2y + 2
x = 2y − 2
