#### Answer

(-17, -8)

#### Work Step by Step

There are two equations that we can use: x=3y+7 and x=2y-1. Since x=3y+7 is already simplified in which one variable is isolated we can substitute this equation into x=2y-1.
x=2y-1
3y+7=2y-1
Combine like terms. Subtract 2y from 3y.
y+7=-1
Subtract 7 from -1.
y=-8
Substitute y=-8 into x=2y-1 to solve for x.
x=2(-8)-1
x=-16-1
x=-17
The ordered pair would then be (-17,-8) since x=-17 and y=-8
