Answer
(2, 5)
Work Step by Step
Use the substitution method to insert the equation for y into the first equation:
2x - 3(4x - 3) = -11
Solve for x:
2x - 12x + 9 = -11
-10x + 9 = -11
-10x = -20
x = 2
Let x = 2 in the second equation to find y:
y = 4(2) - 3 = 5
Check the solution (2, 5) in the first equation:
2(2) - 3(5) = -11
4 - 15 = -11
-11 = -11; True
