y=8, 3y is 24.
-2 = 3y-18-5y 16=3y-5y 16=-2y y=-8
x = 12 and y = 8
If 3y = 12, 2y = 8
3y + 8 = 3 -8 -8 3y=-5 (3y)/3=-5/3 y=(-5/3)
4
y=5
yes.
Yes.
y=8
(0,-4)
Y=-3. -8 on both sides and divide by3 -10 = 8 + 3y -18 = 3y -6 = y or y = -6
Simple system. X + 3Y = 2 2X - 3Y = 22 ------------------------add 3X = 24 X = 8 --------------------now, insert back into one of the equations to find Y 8 + 3Y = 2 3Y = - 6 Y = - 2 ----------------check both equations 8 + 3(- 2) = 2 2 = 2 ---------------top checks 2(8) - 3(- 2) = 22 16 + 6 = 22 22 = 22 ----------------both are consistent, so X = 8 Y = - 2
