Question
Step 2 of 3
The system from Step 1 has a variable with opposite coefficients. Add the equations and solve for the other
variable.
Add the equations to eliminate x. Then use the division property of equality to solve for y.
-118x
4y =
118x
177y =
-5,251
-181у
-5,249
y =
29
29
Step 3 of 3
Substitute the value you found for y in Step 2 into one of the equations from the original system in Step 1.
Then use properties of equality to solve for the other variable, x.
Substitute 29 for y in -59x – 2y = 1. Then use the subtraction and division properties of equality to isolate
the variable.
-59x – 2y = 1
-59x – 2(29)
= 1
-59x =
X =
