What is 5x - 3y -7x plus 2y plus 3x?

5x - 3y -7x + 2y +3x = (5-7+3)x + (-3+2)y = x - y

How do you solve 5X plus y equals -12 7X -3y equals -30 by elimination method?

(1) 5x+y=-12 (2) 7x-3y=-30 From (1) one gets y = -12-5x Put into (2) 7x-3y = 7x -3 (-12-5x) = 7x + 36 +15 x = 22x +36=-30 22x = -30-36 = -66 so x = -3 and y=-12-5x = -12-5x-3= 3 The solution is (-3,3)
