(2x + 3)(2x + 3)
30+12x = 6(5+2x)
2x+5=-91-10x 12x+5=-91 12x=-96 x=-8
2x + (10x - 4) = 20 2x + 10x - 4 = 20 12x - 4 = 20 12x = 24 x = 2
-2x-6= -2x-6Another answer:-2x-6 = 2x+6-2x-2x = 6+6-4x = 12x = -3
12x-3=2x+17 10x-3=17 10x=20 x=2
6x + 12x + 2x = 80 20x = 80 x = 4

(2x + 3)(2x + 3)
30+12x = 6(5+2x)
2x+5=-91-10x 12x+5=-91 12x=-96 x=-8
2x + 3 = -92x = -12x = -6
No solution. Multiply second equation by 3 and get 12x + 6y = 0 but already stated 12x + 6y = 9...
2x + (10x - 4) = 20 2x + 10x - 4 = 20 12x - 4 = 20 12x = 24 x = 2
-2x-6= -2x-6Another answer:-2x-6 = 2x+6-2x-2x = 6+6-4x = 12x = -3
