Steve, I wrote the problems incorrectly, so no, I can't

Welp, my last post I wrote wrong and everyone was answering it wrong... my bad Here are the questions: (3?6 +5?10)^2 y = ?6x-18 I couldn't figure out how to solve them, and I looked up online and here are the answers. I just need to be able to solve it... 286 + 60?15 x ? 3

Algebra 1
Fail. It wrote it wrong. These are the problems: (3?6 + 5?10)^2 y = ?6x-18 I solved the second one. Here are my answers, I just need to know how to solve: 286 + 60?15 x (greater than or equal to) 3

Algebra 1
I know the answers, I just don't know how to solve it and show my work. 1. (3?6 + 5?10)^2 - 286 + 60?15 2. (2 + ?10)(2 - ?10) - -6 3. y = ?6x-18 - x (greater then or equal to) 3 Thank you
