3x + 7 = -x - 1

So, we have 3x = 4 for some number x. We will solve for x. 3x = 4 (1/3)*(3x) = (1/3)*(4) [multiplied by (1/3) on both sides] x = 4/3
3x - x = (3 - 1)x = 2x
{3x +y =1 {x+y= -3
3X^2 + 9X/3X factor out 3X 3X(X + 3)/3X 3X/3X = 1, so... X + 3 is the simplest form here
3x+3=0 -3 = -3 = 3x=-3 /3 /3 x= -1
