What equation is equivalent to 3[x + 3(4x – 5)] = 15x – 24?
39x - 45 = 15x - 24
How do you factor 18x2 plus 39x-15?
divide by 3: 3(6x2 + 13x - 5) Look for factors of 6 which can be multiplied by factors of -5 and added to give 13. Factors of 6: 1 & 6; 2 & 3; Factors of -5: -1 & 5; -5 & 1 the last and first ones give 3 x -5 = -15 and 2 x 1 = 2, total 13 so: 3(3x - 1)(2x + 5) = 3(6x2 - 2x + 15x - 5) = 18x2 + 39x - 15

How do you solve 2-39x-50 equals 4 plus x?
2 - 39x - 50 = 4 + x -39x - 48 = 4 + x Add 39 x to both sides: -48 = 4 + 40x Subtract 4 from both sides: -52 = 40x Divide both sides by 40: x = -1.3
How do you solve X-2x equals 3x-43x plus 1?
For x-2x= 3x-43x+1 x-2x= -x and 3x-43x+1 = -40x+1 so -x= -40x+1 subtract -x from both sides 0= -39x +1 -1 = -39x so 1=39x so x=1/39
