7.76x

Answer 1

Simplify first:

(7x − 2) − (0.04x − 3 + 0.2x)
= (7x − 2) − (0.24x − 3)
= 7x − 2 − 0.24x + 3
= 6.76x + 1

So the equivalent choices are:
- (7x − 2) − (0.24x − 3) (and the same written as "(7x negative 2) negative (0.24x negative 3)")
- 6.76x + 1 (and the same written as "6.76x plus 1")

All other listed options are not equivalent.
