Answer:

the answ

Step-by-step explanation:

It would be 18x-3y=21 then it would be -3y=21-18x than it would be y=21/-3-18x/-3 then the answer would be y=-7+6x than the answer would be y=6x-7

y = 6x - 7

18x - 3y = 21 (add 3y)
18x = 3y + 21 (subtract 21)
18x - 21 = 3y (rearrange so y is on the left and divide by 3)
y = 6x - 7
