To solve this system of equations, we can substitute the expression for y from the second equation into the first equation:
8x - 3(10 + 4x) = -22
8x - 30 - 12x = -22
-4x - 30 = -22
-4x = 8
x = -2
Now that we have found the value of x, we can substitute it back into either of the original equations to solve for y. Let's use the second equation:
y = 10 + 4(-2)
y = 10 - 8
y = 2
Therefore, the solution to the system of equations is (-2, 2).
Solve the system of equations.
8x−3y= −22
y=10+4x (1 point)
