Isolate the x.
Do the opposite of PEMDAS. Note the equal sign. What you do to one side, you do to the other.
2/3x - 2 = 7
Add 2 to both sides
2/3x - 2 (+2) = 7 (+2)
2/3x = 9
Multiply 3/2 to both sides to isolate the x
2/3x(3/2) = 9(3/2)
x = 9(3/2)
Multiply 9 with 3, and divide by 2
9 x 3 = 27
27/2 = 13.5
x = 13.5 is your answer
hope this helps
