First sum the terms with x: 9x + (-3)x = 6 x. Then sum the terms without x: -11 + (-13)x = -24. Then 6x - 24 =0 or x = 24/6 = 4

x - 6x = 0-5x= 0x = 0/-5which equals x = 0
Simply put, No.
So we have x^2 + 3*x = 180 --> x^2 + 3*x - 180 = 0. This can factor into (x-12)(x+15)=0, So x = -15 or x = 12 satisfies it: -15 is the answer. I factored by looking for factors which sum to +3 and multiply to -180
anything x 0 = 0
