7x + 8 = 5x + 327x = 5x + 242x = 24x = 12hope this helps

x=6

5x+32+7x+8=180. By the laws of commutativity we can thus say that 12x+40=180. Subtracting 40 we get 12x=140. Divide by 12 and you get x=(do it yourself) This has nothing to do with calculus by the way.

It is: 12x

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.

7x = 5+5x 7x-5x = 5 2x = 5 x = 2.5

(21x3-23x2-76x-32)/(7x+4) = [3x2(7x4) -5x(7x+4)-8(7x+4)]/(7x+4)=3x2-5x-8

x = -5

7x-5x=8 2x=8 x=4

7X-1=9+5X. add 1 to both sides 7X=10+5X. Subtract 5X and get 2X=10 divide by 2 and x=5

many solutions

It is an equation and the value of x is 8

5x + 17 = 7x - 123 123 + 17 = 7x - 5x 140 = 2x x = 140 ÷ 2 x = 70

7x = 21 x = 3

2x + 5x = 35 7x = 35 x = 35/7 x = 5

18 + 7x - 12 + 5x = ?18 - 12+ 7x - 5x = ?6 + 2x = ?

The answer to the math problem of 5x plus 7x-4x 6 is -12.

If you mean 5x^2 -7x +2 = 0 then it is a quadratic equation with solutions of x = 2/5 or x = 1

5x2+ 7x + 2 = (x + 1)(5x + 2).

sin7x-sin6x+sin5x

1 - 5x + 7x is an expression, not an equation (no equals sign), so you cannot solve for x. You can, however simplify (combine like terms) and get 1 + 2x.
