1. Multiply the first equation by 3:
3(2x) = 3(3y) + 3(9)
6x = 9y + 27
2. Subtract the second equation from the new first equation:
6x - 6x = 9y + 27 - (-5y + 13)
9y + 27 + 5y - 13 = 0
Combine like terms:
14y + 14 = 0
14y = -14
Solve for \( y \):
y = -1
Substitute \( y = -1 \) back into the first original equation:
2x = 3(-1) + 9
2x = -3 + 9
2x = 6
11. Solve for \( x \):
x = \frac{6}{2}
x = 3
Correct Answer:
x = 3
y = -1
