5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3
x = -1.2, y = -3
If: x = 7 Then: y = (2*7)+3 = 17 And: 5x+y = (5*7)+17 = 52
-5x=3+y x=-1/5y-3/5

5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3
5x+8 = 10x+35x-10x = 3-8-5x = -5x = 1 and by substituting the value of x into the equations y = 13
x = -1.2, y = -3
If: x = 7 Then: y = (2*7)+3 = 17 And: 5x+y = (5*7)+17 = 52
-5x=3+y x=-1/5y-3/5

5x - y + 3 = 0can be rewritten as y = 5x + 3 and so the slope is the coefficient of x which is 5.
When 5x+3 = 17 then x = 2.8 Therefore when 8x-y = 3 then x = 2.8 and y = 19.4

Yes.
y = 5x + 3When x=2,y = 5(2) + 3 = 10 + 3 = 13
