Answer and Explanation :
Given : Maria solved the equation below and got x = –4.
To find : Equation verifies that her solution is correct?
Solution :
We have given the equation,

To verify that her solution is correct we substitute x=-4 if LHS=RHS then she is correct.
LHS - 
Put x=-4

LHS=2
RHS - 
Put x=-4

RHS=2
LHS=RHS
The solution is correct.
5(-4)+22 = (-4)+6
-20+22 = -4+6
2 = 2
Maria is correct, since both sides equally match.
