Question

Solve.
a. x - 7 > 10
b. 3x <_ 21
c. 5a - 2 < 18

Answer 1

A. x-7 > 10 You need to isolate a. So you add 7 to both sides.

Answer 2

x > 17?
and how do you do the others?

Answer 3

Correct. Same way. For b:
You need to isolate x again. So since it has 3 times x, you need to do the opposite of multiplication, which would be division. So you divide 3 from both sides.
