Hello, can someone help me solve and check the following

1) x - 8 = 20 Check:

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.

  1. 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.
