Let's look at this system of equations and determine which terms have opposite coefficients. Remember, the coefficients are the number part of the variable term, so the ex coefficients are three and four and the wide coefficients Air seven and negative seven. So those air the opposites. So we'll say the Y terms are the ones that have opposite coefficients.
