You can put this solution on YOUR website!
Solve:
7x + 7 = 6x


7x%2B7=6x
7x-6x%2B7=6x-6x
x%2B7=0
x%2B7-7=0-7
highlight%28x=-7%29
To check your answer, substitute -7 in for x and see if both sides of the equation equal once you simplify.
7%28-7%29%2B7=6%28-7%29
-49%2B7=-42
-42=-42 We're right!!!
Happy Calculating!!!
