Fix the Mistakes
Elba and Jorge each made an error in the first two steps of solving the equation
2(x + 4) - 7 = 21 - 3(2 + x).
Determine the error each student made. Then, solve the equation.
Elba's Work
Jorge's Work
2(x + 4) - 7 = 21 - 3(2 + x)
2(x + 4) - 7 = 21 - 3(2 + x)
2x + 4 - 7=21 - 6+ x
2x + 8 -7 = 21 - 6 + 3x
2x - 3= 15 +2
2x + 1 = 15 + 3x
X - 3 = 15
2x = 14 + 3x
= 18
-x = 14
x = -14
