5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3
x = -1.2, y = -3
It will be any of the equations that has the same slope of y = 5x+9 but with a different y intercept
5x + y = 6 so that y = 6 - 5x Also x +2y = 1 so that x + 2*(6-5x) = 1 or x + 12 - 10x = 1 => 9x = 11 or x = 11/9 and then y = 6 - 5x = 6 - 55/9 = -1/9
y=5x+2 if y equals -4
5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3
x = -1.2, y = -3
Yes.
The equations will have the same slope as y = 5x+9 but a different y intercept

-9
If: 5x+2y = 9 Then: y = -2.5x+4.5 in slope intercept form
y=5x+2 if y equals -4
5x + y = 5
y = 5x + 9
How do you add 2x plus 3y equals 18 in 5x-y equals 11
