Answer: x = 11
Why?

This is a pretty simple equation to figure out. The left side of the equation (1x // 1 * x) is unneeded. So we can rewrite as x + 15 = 26. To find this out, subtract the two numbers known. (26 & 15) Subtract. (26 - 15 = 11) Check: 11 + 15 = 26. This is true.
Hope this helped you! ♥
