Answer:
B. X=76
Explanation:
To solve this problem, first, you have to find the value of x. Remember to solve this problem, isolate x on one side of the equation.
(2x+10)=(86+x)
2x+10=(86+x)
DISTRIBUTIVE PROPERTY:
A(B+C)=AB+AC
A(B-C)=AB-AC
(86+x) (Expand.)
86+x (Remove parenthesis.)
2x+10=86+x
2x+10-10=86+x-10 (Subtract 10 from both sides.)
86-10 (Solve.)
86-10=76
2x=x+76
2x-x=x+76-x (Then, subtract x from both sides.)
76-x (Solve.)
76-x=76
x=76
The correct answer is (B.) 76.
