What is the ordered pair that is the solution to these equations 2x - 3y equals 7 and -3y plus y equals 7?

2x - 3y = 7

-37 + y = 7

The second equation simplifies to -2y = 7 so that y = -7/2

Substituting this value for y in the first equation gives

2x - 3*(-7/2) = 7

2x + 21/2 = 7

or 4x + 21 = 14

so that 4x = -7 and so x = -7/4

So the solution to the given question is (x, y) = (-7/4, -7/2)
