40
To solve the equation 30 - 3 = 40 - x, you first simplify the left side to get 27. The equation now reads 27 = 40 - x. To isolate x, you subtract 40 from both sides to get -13 = -x. Finally, to solve for x, you multiply both sides by -1 to get x = 13.

13 add something equals 30 = 43
The one-step equation that equals 13 is x = 13. In this equation, x represents the unknown value that, when solved, will equal 13. This is a simple linear equation that can be solved by performing the inverse operation, which in this case would be x = 13.

To solve the equation 30 - 3 = 40 - x, you first simplify the left side to get 27. The equation now reads 27 = 40 - x. To isolate x, you subtract 40 from both sides to get -13 = -x. Finally, to solve for x, you multiply both sides by -1 to get x = 13.
To solve for x in the equation 2x - 17 = 13, you first need to isolate the variable x. Add 17 to both sides of the equation to get 2x = 30. Then, divide both sides by 2 to find x = 15.
