A 2-step equation that equals 13 could be: 2x + 7 = 13. To solve this equation, first subtract 7 from both sides to isolate the variable: 2x = 6. Then, divide both sides by 2 to solve for x: x = 3. Therefore, when x = 3, the equation 2x + 7 equals 13.
Dear Questioner its not able to solve two variables for one equation, give one more equation. Thanks
6 x 7 = 4242 - 13 = 29Check:13 + 29 = 42
The two equations 74 + 13 = 87 and 87 - 13 = 74 demonstrate the inverse relationship between addition and subtraction. In the first equation, adding 13 to 74 gives you 87, while in the second equation, subtracting 13 from 87 returns you to 74. This showcases how addition and subtraction are inverse operations, with subtraction "undoing" the action of addition.
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.
