X-3=5 what does x equal

Answer: X = 8

Step-by-step explanation: To solve for x in this equation, we want to get x by itself on the left side of the equation. Since 3 is being subtracted from x, to get x by itself, we need to add 3 to the left side of the equation. If we add 3 to the left side, we must also add 3 to the right side.

Notice that on the left side - 3 and + 3 cancel each other out so we're simply left with x. On the right side, 5 + 3 gives us 8 so we have x = 8.

We can check our answer by substituting 8 back into the original equation. So we have (8) - 3 = 5 or 5 = 5 which is a true statement so our answer is correct.

8

Step-by-step explanation:

x-3=5

add the 3 to both sides of the equal sign

x - (3+3) = (5+3)

x=8
