can someone tell me what type of math this would be called so i can study it or watch a youtube vide

you are asked to solve for x, you can do it by first expanding the LHS using the formula
a(b + c) = ab + ac
so
2x + 10 = 5x - 2
group x terms together and constants together
5x - 2x = 10 + 2
simplify
3x = 12
divide both sides by 3
x = 4
as to what type of math it is, it's called algebra
