3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2

y-3x+6y=12 7y=3x+12 y=3x/7 +12/7

X = 12

3x=12 3x/3=12/3 x=4

4+3x-27=-12 To solve it... 3x= -12-4+27 3x= 11 x= 11/3 x= 3.666

x = 4 and y = 0

15x minus 8=minus 180 3x+8=24

x=7

x = -8

12/3 = 4

2x-12

x2 plus 3x plus 3 is equals to 0 can be solved by getting the roots.

3x+5=20 3x=15 x=5

-3x + 5 = 20 -3x = 15 x = -5

3x+8 = 12 3x = 4 x = 4/3

Multiply first equation by 1.5, giving 3x + 3y = 12, but we are told that 3x + 3y = 6. If there isn't an error in the question then 2 = 1!

Point slope equation: Y=3X+12

x = 6

x = -8

3x+42=6x+12 42=6x-3x+12 42=3x+12 42-12=3x 30=3x 10=x

3x+12=x+48: 3x-x=-12+48 2x=36 x=18

3x - 12 = -2x + 235x = 35 so x = 7
