Answer: [tex]x=11[/tex]
Reorder the terms in parentheses
[tex]+(+2x-10)+7=x+8[/tex]
Remove unnecessary parentheses
[tex]+2x-10+7=+x+8[/tex]
Move all terms containing x to the left and all other terms to the right
[tex]+2x-1x=+8+10-7[/tex]
Simplify left and right side of the equation
[tex]+1x=+11[/tex]
divide both sides of the equation by 1 to get x
[tex]x=11[/tex]
