5x - y = 35
5x - y + y -35 = 35 - 35 + y
5x - 35 = y
There are infinite number of solution, but we need to find some of the solutions by giving some values for x, and after substituting x with them into the equation we can find the corresponding values of y.
Let x = 6, 7, 8
x = 6, y = 5(6) - 35 = 30 - 35 = -5 (6, -5)
x = 7, y = 5(7) - 35 = 35 - 35 = 0 (7, 0)
x = 8, y = 5(8) - 35 = 40 - 35 = 5 (8, 5)

-5y-35 = -4x -5y = -4x+35 y = 4/5x-7 The y intercept is -7
If y equals 5x-15 and x equals 1 then the value of y comes out to be -10. So y equals 5x-15 is -10.
(5 x -7) - (2 x -3) = -35 - (-6) = -35 + 6 = -29
