Question

5x-3y= 47
6x-y= 7

Answer 1

y = -7+6x
5x -3(-7+6x) = 47 (=)
x = -2 and y= -19

Answer 2

can u show me full steps?

Answer 3

This is a system of equations:
If you multiply the second equation by -3 and add the equations together, y will cancel out.
5x - 3y = 47
-18x + 3y = -21
Now you have -13x = 26
So x = -2
Now plug in x into equation 1:
5(-2) - 3y = 47
-10 - 3y = 47
-3y = 57
y = -57/3
