To solve this system of equations, we can use either the substitution method or the elimination method.
Let's use the elimination method to solve this system:
1) x + 8y = -6 2) 5x - 2y = 12
To eliminate one of the variables, let's multiply the first equation by 5 and the second equation by 1: 1) 5(x + 8y) = 5(-6) 2) 1(5x - 2y) = 1(12)
This gives us: 1) 5x + 40y = -30 2) 5x - 2y = 12
Now, we can subtract the second equation from the first: (5x + 40y) - (5x - 2y) = -30 - 12 5x + 40y - 5x + 2y = -42 42y = -42 y = -1
Now that we have found the value of y, we can substitute it back into one of the original equations to solve for x. Let's use the first equation: x + 8(-1) = -6 x - 8 = -6 x = 2
Therefore, the solution to the system of equations is x = 2 and y = -1.
