System of equations A set of equations with the same variables. The solution is where they intersect on a graph; substitution or elimination Substitution -3x - 4y = -2 y = 2x - 5 substitute for y -3x - 4(2x - 5) = -2 -3x - 8x + 20 = -2 -11x = -22 {x = 2} substitute for x y = 2(2) - 5 y = 4 - 5 {y = -1} solution = (2,1) Elimination/addition 2x - 3y = 15 5x + 3y = 27 make sure either both x's OR both y's are the same 2x - 3y = 15 5x + 3y = 27 add to get rid of y...
