-6x + 12y = -102 -6x = -12y - 102 x = 2y + 17
3y + 4z + 12y = 3y -3y -3y ------------------------- 4z + 12y = 0 divide everything by 4 z + 3y = 0 -3y -3y z = -3y
y = 11
x = 2 and y =-3 so the lines intersect at (2, -3)
Answer:12y=132y=132/12=11
12y + 5 = 53 12y = 48 y = 4
-6x + 12y = -102 -6x = -12y - 102 x = 2y + 17
12y+2=146 12y=146-2 12y=144 144/12 12x12=144 y=12
12y - 4 = 7y + 165y = 20y = 4
12y = 8x + 24 so y = 2x/3 + 2
6y + 4.. i think
12y + 2 or 2*(6y+ 1)
its 10x +9y +1z
3y + 4z + 12y = 3y -3y -3y ------------------------- 4z + 12y = 0 divide everything by 4 z + 3y = 0 -3y -3y z = -3y
dont know sorry
13x - 9y - 10
negative one and a half
