Well, darling, the answer to that little math problem is x = -4. You just gotta combine like terms, move the variables around, and voila! You've got your solution. Math might not be everyone's cup of tea, but hey, it's all about following those rules and getting to the right answer.
3x + 2x = 5x. 5x= (-4) X = (-4)/5 x= -0.8
5x - 4 = 3x + 6 5x - 3x = 6 + 4 2x = 10 x = 5
5X + 6 = 2X + 15 -2X -2X 3X + 6 = 15 -6 -6 3X = 15 ---- ----- 3 3 x = 5 im so smart.
2x + 5 + 3x = 25 5x + 5 = 25 Subtract 5 from both sides: 5x = 20 Divide both sides by 5: x = 4
5x
3x + 2 + 2x = 7; 3x + 2x = 5x, so 5x + 2 = 7; 7-2=5, so 5x=5. 5x divided by 5 and 5 divided by 5 equals 1, so x equals 1.
7x = 5+5x 7x-5x = 5 2x = 5 x = 2.5
2x + 5x = 35 7x = 35 x = 35/7 x = 5
5x - 2x = -5 - 1 ie 3x = -6 so x = -2
x+2x+14=5x+214-2=5x+2x+x10=8x10/8=xx=5/4 ans.
x = -5
5
3x+5=4-2x+6 5x=4-1 5x=3 x=3/5
3x + 2x = 5x. 5x= (-4) X = (-4)/5 x= -0.8
-3x + (-18) = 2x + 7 +18 +18 -3x = 2x +25 -2x -2x -5x = 25 ----- ----- -5 -5 x=-5 *------- equals a division line
2x + 5x = 357x = 35x = (35 / 7) = 5
x=1 2/3 How?: 2x-4+3 = 5x-6 2x-1 = 5x-6 2x-1+1 = 5x-6+1 2x = 5x-5 2x-5x = 5x-5x-5 -3x = -5 -3x/-3 = -5/-3 x = 5/3 x = 1 2/3
