Celia uses the steps below to solve the equation
(-8-18d) + 20 - 24
Distribute
Step 1
over the expression in parentheses,
Step 2
Step 3
3-16d+ 20-24
Simplify like terms
3-14d=24
Subtract 3 from both sides of the equation,
-140=21
Divide both sides of the equation by --14
Step 4
Which corrects the error in the step in which Celia made the first error?
In step 1, she should have also distributed - over 2d to get 3-16d+
20 = 24
