7 x − 3 y = 24 7 x − 3 ⋅ ( − 5 6 x + 2 ) = 24 7 x + 5 18 x − 6 = 24 5 35 x + 5 18 x = 24 + 6 5 53 x = 30 / ⋅ 53 5 x = 53 150
y = − 5 6 x + 2 y = − 5 6 ⋅ 53 150 + 2 y = − 53 6 ⋅ 30 + 2 y = − 53 180 + 53 106 y = − 53 74 A n s w er : x = 53 150 an d \y = − 53 74
The solution to the system of equations is x = \frac{150}{53} and y = -\frac{74}{53}. This was found using the substitution method, first isolating y and then substituting into the second equation. Each step involved simplifying and solving for the variables properly.
