X+7=10

surely you know what added to 7 makes 10 ...

But, if you want to do the algebra, start by subtracting 7 from both sides, so you get x all alone.

To solve for X in the equation X + 7 = 10, you need to isolate X on one side of the equation. Here are the step-by-step instructions:

Step 1: Start with the equation X + 7 = 10.

Step 2: Subtract 7 from both sides of the equation to isolate X. This gives us:
X + 7 - 7 = 10 - 7.

Simplifying the equation:
X = 3.

Step 3: The solution to the equation X + 7 = 10 is X = 3.

To solve the equation X + 7 = 10, you need to isolate the variable X on one side of the equation. Here's how to do it step by step:

Step 1: Start with the equation X + 7 = 10.

Step 2: To isolate X, subtract 7 from both sides of the equation:
X + 7 - 7 = 10 - 7
X + 0 = 3
X = 3

Step 3: The solution to the equation X + 7 = 10 is X = 3.

So, the value of X that satisfies the equation is 3.
