x = 13

Answer 2

To solve the equation x - 3 = 10 using mental math, you want to isolate the variable x. To do this, you can add 3 to both sides of the equation to cancel out the -3:

x - 3 + 3 = 10 + 3
x = 13

So the solution is x = 13.

Answer 3

To find the solution to x - 3 = 10 using mental math, you can isolate x by adding 3 to both sides of the equation. This will give you:

x - 3 + 3 = 10 + 3

Simplifying this equation, you get:

x = 13

So the solution to x - 3 = 10 is x = 13.
