5y - 3y = 18 2y = 18 y = 18/2 y = 9
No.
The question is not quite clear, do you mean -6x+3y = -18 and -10+5y = -30? If so then the solution is: -10+5y= -30 5y = -30+10 5y = -20 y = -4 Substitute the value of y into the equation -6x+3y = -18: Answer: x = 1 and y = -4
x = 3 and y = 2

Solve this system of equations. 5x+3y+z=-29 x-3y+2z=23 14x-2y+3z=-18 Write the solution as an ordered triple.
How do you add 2x plus 3y equals 18 in 5x-y equals 11
2x plus 3y
5y - 3y = 18 2y = 18 y = 18/2 y = 9
No.
(10,13)
(x, y) = (3, 7) is a solution.

30 - 12 = 18
3y + 18 = -8x + 3Subtract 18 from each side:3y = -8x - 15Divide each side by 3:y = (-8/3)x - 5
