x could be 2 and y could be 1
5x+y=-7 3x+y=15 8=D
x = -3, y = 7
(1, 1)
51
Their graphs are.
5x+y=-7 3x+y=15 8=D
The slope of y is -3x, hope that help
y-3x+6y=12 7y=3x+12 y=3x/7 +12/7
4x - y = 1 3x + y = 13 Simultaneous Equations. Add ; This will eliminate 'y' Hence 7x = 14 x = 2 When x = 2 3(2) + y = 13 6 + y = 13 y = 13 - 6 y = 7 Hence the solution in ( x,y) form is ( 2, 7).
x = -3, y = 7
No because they don't have the same slope (9x & 3x)

Substitute y = 0 in the equation: 0 = 3x + 7 so that x = -7/3
3x+2y-7=0 2y=-3x+7 y=1/2(-3x+7) or -3/2 x +7/2
