3x-2 = 2x+3 3x-2x = 3+2 x = 5

-1-2x-4x=19-6x-1 = -19x = 3

Add 5 to both sides of the equation to get rid of the - 5. -3x - 5 + 5 = -20 + 5 Solve and simplify. -3x = -15 Divide both sides of the equation by -3. x = 5

2x - 4 = -10 2x = -10 +4 2x = -6 x = -3

x + 3 = 11 (to solve for x, subtract 3 fromeach side of the equation) x + 3 - 3 = 11 - 3 (then simplify) x = 8 (this is the answer)

You cannot solve one linear equation with two variables.

You would do it it by oppisites. 3+2+4=9 which equals C.

Since the second equation is already solved for "y", you can replace "y" by "9" in the other equation. Then solve the new equation for "x".

It is not possible to solve one linear equation in two unknown variables.

You need another equation to make this a linear equation so you can solve for both variables. One equation with two variables is not enough to determine the correct answer.
