x + 2 = -2x + 2
Add 2x to each side of the equation:
3x + 2 = 2
Subtract 2 from each side:
3x = 0
Divide each side by 3:
x = 0
The equation is a true statement only if x=0.

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
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
