Answer 3

How do you isolate the variable? I wasn't there when we learned this in school so I'm not sure.

Answer 4

ok I'll give an example

2 + 10x = 48
you need to move everything to the other side of the equation to get the value of x
first, subtract 2 on both sides

so now you have 10x = 50
now divide both sides by 10
x =5
