y = 2x -1 y = 5x -13 So: 5x -13 = 2x -1 5x -2x = 13 -1 3x = 12 x = 4 and by substituting y = 7
Add: 5x - y + x + y + 8 + 10 ie 6x = 18 so x = 3 and y = 7
16
If x=6 and y=8, then [ 5x + 8y ] = 5(6) + 8(8) = 30 + 64 = 94
5x - 8 = yWhen y = 1,5x - 8 = 1Add 8 to each side of the equation:5x = 9Divide each side by 5:x = 9/5 = 1.8
5x-y equals 18 = -13
50
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
[5x+13]
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
(0,0)
The origin.
y = 5x + 9
