if 3x = 21 all you have to do is divide both sides of the equation by 3

3x = 21

3x divided by 3 is x, and 21 divided by 3 is 7

so then you get x = 7

PLLLLLLZZZZ HELP!! MULTIPLE CHOICE!!
liubo4ka [24]
First, set 2x+7 equal to 3x-7 since they are the same angle due to the parallel lines.

2x+7=3x-7
x=14

Then, since 2x+7 and 12y+1 equals 180, put it together to find y:

(2x+7)+(12y+1)=180
(2(14)+7)+(12y+1)=180
12y+1=145
12y=144
y=12

So, x=14 and y=12. Your answer should be C!
