Question

*50 points* Pls help. Pls answer both part A and Part B. Look at the picture for question.

Answer 1

Eleanor has made an error in Step 1

She clearly intended to multiply both sides by 2, but forgot to multiply the
`-9x` part of the RHS.

Step 1 should be:
`x+18=8(2x-6)-18x`

Correct solution

Given:
`\frac12(x+18)=4(2x-6)-9x`

Step 1:
`x+18=8(2x-6)-18x`

Step 2:
`x+18=16x-48-18x`

Step 3:
`x+18=-48-2x`

Step 4:
`66=-3x`

Step 5:
`x=-22`
