2x + y = 7y = -2x + 7
your equation is this... 2x < y + 7 Now solve for y... 2x - 7 < y Since you have two variable the most you can get out of (y) is the graph and the y-intercept. the y-intercept is y > -7
(3, 1)
If you mean: y = 3x+5 and y = 2x-7 then x = -12 and y = -31
If: x = 7 Then: y = (2*7)+3 = 17 And: 5x+y = (5*7)+17 = 52
2x + y = 7y = -2x + 7
y=2x+7. The 2 is your slope and the 7 is your y intercept.
2x(y - 3) + 7(y - 3) = (2x + 7)(y - 3)
your equation is this... 2x < y + 7 Now solve for y... 2x - 7 < y Since you have two variable the most you can get out of (y) is the graph and the y-intercept. the y-intercept is y > -7

y=f(x)= x(2x+y)=7 f(x)=2x^2 +xy -7 = 0 y=2x^2 +xy -7 y-xy -7 + 2x^2 = 0 y(1-x)=2x^2-7 y=(2x^2-7) / (1-x) Excuse the working. Y equals 2 X squared minus 7 all divided by 1-X
If you mean: y = 3x+5 and y = 2x-7 then x = -12 and y = -31
2x = y + 7 x - 2 = y substitute the y from the second equation into the first: 2x = x - 2 + 7 2x = x+5 x = 5 --> y = 5 - 2 y = 3
-5
If: x = 7 Then: y = (2*7)+3 = 17 And: 5x+y = (5*7)+17 = 52
