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

-5y-35 = -4x -5y = -4x+35 y = 4/5x-7 The y intercept is -7
5x-y equals 18 = -13
5x - 7y = -35At the x-intercept, y=0:5x = -35x = -7At the y-intercept, x=0:-7y = -35y = 5
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.
Yes.
5x=11y
(5 x -7) - (2 x -3) = -35 - (-6) = -35 + 6 = -29

y = 2x -1 y = 5x -13 So: 5x -13 = 2x -1 5x -2x = 13 -1 3x = 12 x = 4 and by substituting y = 7
7
5x + y = 5
