Question

Lin solved the equation 8(x-3)+7=2x(4-17) incorrectly.

Find the errors in her solution. What should her answer have been?

Lin's Steps - 8 (x-3) + 7 = 2x (4 - 17)
8 (x-3) + 7 = 2x (13)
8x - 24 + 7 = 26x
8x - 17 = 26x
-17 = 34x
-1/2 = x

Answer 1

Answer:

22

Step-by-step explanation:

Answer 2

Answer:

1/2 = x

Step-by-step explanation:

8 (x-3) + 7 = 2x (4 - 17)

8 (x-3) + 7 = 2x (-13)

8x - 24 + 7 = -26x

8x - 17 = -26x

-17 = -34x

1/2 = x
