To solve the system of equations, substitute the value of y from the second equation into the first equation:
8x - 3(10 + 4x) = -22
8x - 30 - 12x = -22
Combine like terms:
-4x - 30 = -22
Add 30 to both sides:
-4x = 8
Divide both sides by -4:
x = -2
Now, substitute the value of x back into the second equation to find y:
y = 10 + 4(-2)
y = 10 - 8
y = 2
So, the solution to the system of equations is (x, y) = (-2, 2).
8x - 3(10 + 4x) = -22
8x - 30 - 12x = -22
Combine like terms:
-4x - 30 = -22
Add 30 to both sides:
-4x = 8
Divide both sides by -4:
x = -2
Now, substitute the value of x back into the second equation to find y:
y = 10 + 4(-2)
y = 10 - 8
y = 2
So, the solution to the system of equations is (x, y) = (-2, 2).

To solve the system of equations, you can use the method of substitution or elimination. Let's use the method of substitution.
From the second equation, we can solve for x:
x = 22 + 6y
Now substitute this value of x into the first equation:
5(22 + 6y) + 2y = 14
Distribute multiplication:
110 + 30y + 2y = 14
Combine like terms:
32y + 110 = 14
Subtract 110 from both sides:
32y = -96
Divide both sides by 32:
y = -3
Now substitute the value of y back into the second equation to find x:
x - 6(-3) = 22
x + 18 = 22
Subtract 18 from both sides:
x = 22 - 18
x = 4
So, the solution to the system of equations is (x, y) = (4, -3).
From the second equation, we can solve for x:
x = 22 + 6y
Now substitute this value of x into the first equation:
5(22 + 6y) + 2y = 14
Distribute multiplication:
110 + 30y + 2y = 14
Combine like terms:
32y + 110 = 14
Subtract 110 from both sides:
32y = -96
Divide both sides by 32:
y = -3
Now substitute the value of y back into the second equation to find x:
x - 6(-3) = 22
x + 18 = 22
Subtract 18 from both sides:
x = 22 - 18
x = 4
So, the solution to the system of equations is (x, y) = (4, -3).
