Answer:
3x+3y−z−7
Step-by-step explanation:
"Let's simplify step-by-step.
4x+2y−z−(x−y+7)
Distribute the Negative Sign:
=4x+2y−z+−1(x−y+7)
=4x+2y+−z+−1x+−1(−y)+(−1)(7)
=4x+2y+−z+−x+y+−7
Combine Like Terms:
=4x+2y+−z+−x+y+−7
=(4x+−x)+(2y+y)+(−z)+(−7)"(Mathpapa)
Are you sure you wrote it right because it should be -42.99
