9x+6 = 6x+15 9x-6x = 15-6 3x = 9 x = 3
6x-7 = 3x+5 6x = 3x+12 (subtracting -7) 3x=12 (subtracting 3x) x=4 (dividing by 3)
Watch closely:6x = 3x + 27Subtract 3x from each side:3x = 27Divide each side by 3:x = 9
6x^2 + 11x + 4 is a Quadratic Statement. It is NOT an equation, because there is no 'equals' (=). It will factor to ( 3x + 4)(2x + 1)
It is: 3x+4
