It's a linear equation in 'x'.It has exactly one solution.Here's how to find it:-6x = 30Divide each side by -6:x = -5

It is an equation and the value of x is -5

16x+9 without the rest of the equation, what this equals, I can't solve

-20 = -4x - 6x-20 = -10x20 = 10x2 = x

-10 = 6x - 16, or 16 - 10 = 6x, or x = 1.

If 6x + 10 = 11x , then x=2.

6x-20 = 8x 6x-8x = 20 -2x = 20 x = -10

you just only need the first 2 parts of the equation! 6x-10=10x so you have to minus 6x each side: so 6x-6x-10=10x-6x, so it turns to -10=4x. Then you have to divide -10 by 4. so -10/4=-2.5 so x is -2.5.

-20 = -4x - 6x -20 = -10x -20 / -10 = -10x / -10 2 = x x = 2

x=-8

The question is not quite clear, do you mean -6x+3y = -18 and -10+5y = -30? If so then the solution is: -10+5y= -30 5y = -30+10 5y = -20 y = -4 Substitute the value of y into the equation -6x+3y = -18: Answer: x = 1 and y = -4

From first equation y = 3x + 5. Substitute this in second equation 2(3x + 5) = 6x + 10 This proves that 6x + 10 = 6x + 10 which is not helpful! I suppose possible solutions would be x = 0, y = 5 or x = 1, y = 8 etc etc Are you sure of your two equations, please?

x=10 For the equation -9 - 6x +7x = 1 First, add nine to both sides to get all of the x's on one side -9 - 6x + 7x = 1 +9 +9 -6x +7x = 10 Then, combine like terms on the left side -6x+7x=10 x=10
