Use the elimination method to solve the system of equations .
9x - 7y = 22
x + 3y = -24
First, multiply the second equation by 9:
9(x + 3y) = 9(-24)
Expanding the equation:
9x + 27y = -216
Next, add the first equation to the modified second equation:
9x - 7y + 9x + 27y = 22 - 216
Combining like terms:
18x + 20y = -194
Now you have a single equation:
18x + 20y = -194
You can solve this equation for either x or y to get the values of x and y.
