Q. Solve using elimination.−8x−8y=−16−8x−9y=−13(_____, _____)
Write Equations: Write down the system of equations.−8x−8y=−16−8x−9y=−13
Eliminate Variable: Decide which variable to eliminate. We can eliminate the variable x by adding the two equations because the coefficients of x are the same in both equations.
Add Equations: Add the two equations together to eliminate x.(–8x−8y)+(–8x−9y)=(–16)+(–13)This simplifies to:–16x−17y=–29
