Answer :

2x + 4 = 8
2x = 8 - 4 = 4
x = 4/2 = 2
x = 2

Answer:

x=2

Step-by-step explanation:

Addition property of equality is adding the same number to both sides of an equation does not change the equation.

Subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.

Multiplication property of equality is multiplying both sides of an equation by the same number does not change the equation.

Division property of equality is dividing both sides of an equation by the same non-zero number does not change the equation.

We start with 2x+4=8.  To solve single-variable equations like this one, we want to isolate the x by moving all of the other numbers to the other side of the equation. Since four is the only other number on the left side, we subtract four from both sides of an equation. This gives us, 2x+4-4=8-4, so 2x=4. Now, to find x, we want to just have one x on the left side instead of two, so we divide the equation by two from both sides of an equation. 2x/2=4/2, so and the final answer is x=2 and 2=x.

Hope this helps!
