Combine like terms first. So add the one with X and then add the other two numbers together like (2x+3x) will give you 5x then (36-5) which will give you 31 and you divide 5 from 31 but it will give you a decimal so it would be 6. I’m not sure if I’m right but that’s how I would do it. I hope it kinda made sense on how to kinda solve it :)!
