4 + x = 2x
Subtract 'x' from both sides
4 = 2x - x
x = 4
Verification
4 + 4 = 2(4)
8 = 2 x 4 = 8

Solve this system of equation using substitution 2x plus 6y equals 24 and 3x-2x equals 24?
Solve this system of equation using substitution 2x plus 6y equals 24 and 3x-2x equals 24 ?Improved Answer:2x+6y = 243x-2x = 24 => x =24Substitute the value of x into the top equation to find the value of y:48+6y = 246y = 24-486y = -24y = -4So: x = 24 and y = -4
What does x equals if the sum is 8x plus 8 equals 2x plus 38?
Set up the equation and solve: 8x + 8 = 2x +38 (subtract 2x and 8 from both sides of the equation) 6x = 30 (divide both sides of the equation by 6) x = 5

A single linear equation in two variables cannot be solved.
If 2x plus 2x equals 40 what does x equal?
To solve for x, set up the equation: 2x +2x = 40 (then simplify) 4x = 40 (then divide both sides of the equation by 4) x = 10 (this is the answer)
How do you solve 2x plus 5 -5?
2x + 5 - 5 = 2x. You can not solve for x because this is not an equation.
