To solve this equation, we are going to isolate the variable x. To do this, we are going to begin by adding x to both sides because this will cancel out the negative x on the right side of the equation.
x + 2 + x = -x + x - 2 When we combine like terms, we get: 2x + 2 = -2 Next, we will try to continue to isolate the variable by subtracting 2 from each side to get the 2x term on the left by itself. 2x + 2 -2 = -2 -2 When we combine like terms, we get: 2x = -4 Finally, to get x by itself we must divide by 2 to undo the multiplication of the coefficient of the term 2x. 2x/2 = -4/2 When we perform the division, we get: x = -2 Therefore, x = -2. We can check this answer by plugging it back into the original equation. Our answer is verified because 0=0. Your answer is that x = -2. Hope this helps!
