Hello, can someone help me solve and check the following

2) x + 15 = 35 Check:
3) x +6 = 3 Check:
The symbol 'x' is in italic. If I can understand the symbols better, I belive I can get the hang of the course.

x is a variable, meaning that the value it represents can change. Given the equations, your goal is to find its value.
1)
x  8 = 20
Add 8 to both sides to isolate x.
x  8 + 8 = 20 + 8
x = 28
And that is the value of x in problem 1). Try the other problems.
