Angie made an error in the second step when she subtracted 7 from both sides of the equation.
The correct second step would be:
-7 - (-7) (subtracting 7 from both sides)
x = 11 - 7 (simplifying)
x = 4 (final answer)
Angie is solving the equation-x+7=11
-7-7
X=-18-11-7=-18
In which part of the solution if any, did Angie make an error?
