Here you divide the number from denominator to numerator. Example 3/3=1, 8/2=4 in denominator and 1 in numerator since 2/2=1
First convert the first equation to combine like terms. Then set your equations up as an addition problem. You want at least one of your variables (y) to be of opposite values so the will cancel out to leave you with just one variable (x). Plug in 1/3 for the x into one of the equations to solve for y. Then write as an ordered pair.
