Use any method to solve the system.
|-x + 4y = -26
3x + 4y = -18
Step 1
Equation 1: -x + 4y = -26
Equation 2: 3x + 4y = -18
Note that since the y-coefficients have the same numerical value, the method of elimination is the best way to
solve the system. Subtract Equation 2 from Equation 1 to eliminate the y-terms and solve for x.
To subtract Equation 2, multiply it by -1 and then add. Remember to multiply each term. Write the resultant
equation after combining the like terms.
Equation 1:
-x +
4y = -26
Revised Equation 2:
4y = 18
Resultant Equation:
-
Solve for x by dividing both sides of this equation by the same number.
X =
