8x-7 plus 2x equals 6 plus 5x plus 2?
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.
x 5x-3x +6=-12, x 2x +6=-12,3x+6=-12, move the x and it's very easy 12/6=2 ...But the answer is negative so the x is equal to -2 and the answer is -12...I .

x=6Solution:x + 2x + 14 = 5x + 214 - 2 = 5x - 3x12 = 2xx = 12/2 = 6
5x + 2 = x + 12 5x - x = 12 - 2 4x = 10 x = 10/4 x = 5/2 or 2.5
5x - 10 = 3x + 2 5x - 3x = 2 + 10 2x = 12 x = 12/2 x = 6

3(x + 2) = 5x - 12 3x + 6 = 5x - 12 6 = 2x - 12 6 + 12 = 2x x = 9
X=1.42857142857143
7x + 12 = 5x + 2 Subtract '12' from both sides Hence 7x = 5x -10 Subtract '5x' from both sides. 2x = -10 Divide both sides by '2' Hence x = -5 .
8x-7 plus 2x equals 6 plus 5x plus 2?
The 7x and the 5x are like terms. This means that you can add them up. Think about it, 7 x's plus 5x's equals 12x's. From there, you can divide 12 from both sides of the equation, and you will get that x = 2.
15,000 to the third power that equals pi plus 12 would make it the square root of 7
x+2x+14=5x+2 3x+14=5x+2 (add x's on same side)3x+12=5x (-2 from both side)12=2x (-3x from both sides)2x=12 (turn around for tidyness :P)x=6 (divide each side by 2 to get answer)
f(x)=5x+2
