Answer:
x = 30
Explanation:
To solve the equation means to solve for the variable x. To solve for x, you must isolate the variable. This means to move all terms attached to x to one side of the equation, and all terms not attached to x to the other side. This is simple to do.
2x - 23 = x + 7
2x - 23 - x = x + 7 - x
x - 23 = 7
x - 23 + 23 = 7 + 23
x = 30
Always make sure to check your work when working with variables.
2x - 23 = x + 7
2(30) - 23 = 30 + 7
60 - 23 = 37
37 = 37
37 = 37 is true. The solution x = 30 is thus correct.
