How to do it step by step and solving it

Use the distributive property to eliminate parentheses.

... 2x - (3/4)·2x - (3/4)·80

... 2x -(3/2)x - 60 . . . . . simplify the terms involving fractions

... x(2 - 3/2) - 60 . . . . . identify the x coefficients you need to add together

... (1/2)x - 60 . . . . . . . . simplified form

You have not shown an equation, so there is nothing here to solve.
