It is an equation and the value of x is 91
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.
It is an equation and the value of x is 2.2
It is an equation and the value of x is 13/3
It is an equation and the value of y is 18
6 x 7 = 4242 - 13 = 29Check:13 + 29 = 42
1 + 12 = WHAT

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.
The answer will depend on the relationship between x and y. Since you have chosen not to share that information, it is not possible to give a more precise answer.
1 + 12 = 13
