b) Find the error and describe it in words and then solve the problem correctly:
Simplify: 8(4x – 1) – 3(2x – 5)
Answer: 8(4x – 1) – 3(2x – 5)
= 8(4x) + 8(-1) – 3(2x) – 2 (5)
= 32x – 8 – 6x -15
= 26x – 23
Question 3
a) Simplify: 20(x − 4) − 5x
b) Evaluate: 8 (5 y − 3) = 40 y – 24
c) Solve: 2x − 3(x – 5) = 5(3 + x)
