#### Answer

(2, -1)

#### Work Step by Step

Substitute the equation for y in terms of x into the second equation:
2x - 3(3x - 7) = 7
Solve for x:
2x - 9x + 21 = 7
-7x + 21 = 7
-7x = -14
x = 2
Let x = 2 in the first equation to solve for y:
y = 3(2) - 7 = -1
Check the solution (2, -1) in the second equation:
2(2) - 3(-1) = 7
4 + 3 = 7
7 = 7; True
