Check my answer? I needed to make these equations into y = mx + b form: 42x  4y = 3, 21x = 2y  3, and 21x = y + 3/2.
My answer for #1: y =  10.5x  (3/4). For #2: y = 10.5x + 1.5, For #3: y =  21x + 3/2.

Best ResponseYou've already chosen the best response.1I subtract 42x from both sides and get  4y =  42x + 3, then I divide everything by  4, to isolate y and get y =  10.5x  (3/4).

Best ResponseYou've already chosen the best response.1sounds good, except 42x/4 is not 10.5x

Best ResponseYou've already chosen the best response.1for the last question 21x = y + 3/2 subtact 3/2 from both sides 21x  3/2 =y or y = 21x 3/2
