Question

Describe the error in solving the inequality. Then state the correct answer.-134 < 8X – 5(1 – 7x)-134 < 8x – 5 + 35X-134 < 43x – 5-129 < 43x X > -3

Answer 1

For this case we need to identify the error and provide the correct solution

-134 < 8X – 5(1 – 7x)

This step is correct

-134 <8x-5 + 35X

This step is also correct after distribute the terms

-134 < 43x – 5

This step is also correct after simplify

-129 < 43x

After add 5 in both sides we got -129 in the left so it's right this step

X > -3 (Possible error)

The correct way it would be:

[tex]-\frac{129}{43}
