- x - 3( x - 2 ) = 3 ( 2 - x )
Multiply 3 with x - 2 on LHS and 3 with 2 - x on RHS
Now take -3x to LHS and change its symbol to +. And take 6 to RHS and change it to negative.
-3x and 3x will cancel out and also 6 and -6 will also get cancelled out.

It will cost $33.
Since wood cost $ .60 sq ft, you can assume she needs to buy 55 sq ft because she will need to buy enough to have 54.3 square ft.
55 x $ .60 = $33
$32.58 would be he total for the 54.3 sq ft and .42 cents would be for the left over .7 sq ft that she didn’t use
0.7hr(60min/hr)=42 min
The ration you multiplied by was 60min/hr, to cancel out the hr unit label...
