Answer:

error in step 1

Step-by-step explanation:

$\frac{1}{2}$ (x + 18) = 4(2x - 6) - 9x

Multiply through by 2 to clear the fraction

x + 18 = 8(2x - 6) - 18x

[ Eleanor made the error in not multiplying - 9x by 2 ] ← ←

x + 18 = 16x - 48 - 18x

x + 18 = - 2x - 48 ( add 2x to both sides )

3x + 18 = - 48 ( subtract 18 from both sides )

3x = - 66 ( divide both sides by 3 )

x = - 22
