y = 5x is the equation of a line. Subtitute any value for "x", then calculate the corresponding value of "y", which in this case is simply the value of "x" multipled by 5.
Both equations are equal to each other and when solved x = -3/5 and y = 1
5x-y equals 18 = -13
If: y = -5x+3 then the points are (2, -7) and (6, -27)
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.
That depends on what the value of x is.
Yes.
5x=11y
-10
y = 2x -1 y = 5x -13 So: 5x -13 = 2x -1 5x -2x = 13 -1 3x = 12 x = 4 and by substituting y = 7
[5x+13]
