Taylor Swift solved the equation below. Her work is shown under the problem. Solve:
7(x - 4) – 3x + 2 = 3x - 2 - x
Student Work:
7(x-4)- 3x +2 = 3x - 2-X
7x - 28 - 3x +2 = 4x-2
4x-26 = 4x-2
+26 +26
4x = 4x + 24
-4x - 4x
0= 24
X = no real solutions
Did Taylor make any errors? Ifso, what was it?
A) Yes, she did not distribute correctly.
B) Yes, she did not combine like terms correctly on the right side of the equation.
C) Yes, she did not combine like terms correctly on the left side.
D) Yes, she made an error in the last step. 4x minus 4x is not 0, it is x.
E) Nothing is incorrect about this problem.
