Solve using the elimination system (ordered pairs)
Thank you for the opportunity to help you with your question! Hope your day is going well!
The goal of the elimination method, is to get a common coefficient, for the two equations, and subtract them to get a variable by itself.
Step 1: Notice that 8y is the same in both equations, thus all we have to do is subtract the two equations.
2x=18 (divide by 2 from both sides)
Step 2: Substitute x=9 into the first equation to solve for y
9+8y=57 (subtract 9 from both sides)
8y=48 (divide by 8 from both sides)
Check your work!
Thus your coordinate pair is (9,6)
