-0.38z -0.08

1) To find an expression with the same value as that one, let's evaluate it

(0.32z-0.4)-(0.7z-0.32) Removing the parentheses

0.32z -0.4 -0.7z +0.32 Combine like terms

0.32z -0.7z -0.4+0.32

-0.38z -0.08

2) Hence, the expression equivalent to (0.32z-0.4)-(0.7z-0.32) is -0.38z -0.08
