Answer:
x=-8
Steps:
Simplify-
−3(−7−x)= x+2/2
Simplify-
−3(−7−x)= 1+ x/2
Multiply both sides by 2-
−6(−7−x)=2+x
Expand-
42+6x=2+x
Subtract 2 from both sides-
42+6x−2=x
Simplify-
6x+40=x
Subtract 6x from both sides-
40=x−6x
Simplify-
40=−5x
Divide-
-40/5=x
Simplify-
-8=x
Switch sides-
x=-8
I believe this is correct, if not let me know and I will fix it.
