two options:
if you meant 10x+12x-26 your answer: 22x - 26.
Why?: 10x + 12x - 26 = 22x - 26. This is an algebraic expression which can be simplified to 22x - 26. This expression represents the sum of two terms, 10x and 12x, minus 26.
if you meant 10x=12x-26 your answer: x=13
Why?: 10x = 12x - 26 is an algebraic equation. To solve this equation, you can add 26 to both sides to get 10x + 26 = 12x. Then, subtract 10x from both sides to get 26 = 2x. Finally, divide both sides by 2 to get x = 13. Therefore, the solution to this equation is x = 13.
