Question13. {6x3y=214x=3y9\left\{\begin{array}{l}6 x-3 y=-21 \\ 4 x=3 y-9\end{array}\right.

Studdy Solution
Verify the solution by substituting x=6 x = -6 and y=5 y = -5 back into the original equations:
First equation: 6(6)3(5)=21 6(-6) - 3(-5) = -21 36+15=21 -36 + 15 = -21 21=21 -21 = -21 (True)
Second equation: 4(6)=3(5)9 4(-6) = 3(-5) - 9 24=159 -24 = -15 - 9 24=24 -24 = -24 (True)
Both equations are satisfied, so the solution is correct.
The solution to the system is x=6 x = -6 and y=5 y = -5 .
