Solving Systems of Linear Equations by Addition Examples Page 2

For the following system of equations, eliminate the variable y from the system to get an equation involving only x.

Multiply the first equation by 4 and the second equation by -3 to find

then add for -5x = 17. There are other correct ways to eliminate x, but they should all lead to the solution . No way of avoiding the fraction, sorry. There are plenty of incorrect solutions that lead elsewhere, however, if that makes you feel any better.
