We can substitute the second equation into the first equation:
8x - 3(10+4x) = -22
Simplifying this expression, we get:
8x - 30 - 12x = -22
Combining like terms, we get:
-4x = 8
Dividing both sides by -4, we get:
x = -2
Now that we have x, we can substitute it into either of the two equations to find y. Using the second equation:
y = 10 + 4(-2)
y = 10 - 8
y = 2
Therefore, the solution to the system of equations is (x,y) = (-2,2).
Solve the system of equations.
8x−3y= −22
y=10+4x(1 point)
