Answer:
the answer should be h=22 so i would say step 1
Step-by-step explanation:
The mistake was in Step 1.
An equation is a mathematical statement that is formed when two algebraic expressions are equated using an equal sign.
The equation is
(1/2) (2h-4) = 20
2h-4 = 40
2h = 44
h = 22
The mistake was in step 1, where Nigel should have multiplied 20 by 2 and not divide it by 2.
