Question

6m + 3z + 4m + 2w - 5z; 10m - 2z + 2w; 10m + 2z - 2w; m + z + w; 2m - 2z + 2w

Explanation:

Step1: Combine like terms for $m$

$6m + 4m = 10m$

Step2: Combine like terms for $z$

$3z - 5z = -2z$

Step3: Keep the $w$ term unchanged

$2w$

Step4: Combine all simplified terms

$10m - 2z + 2w$

Answer:

$10m - 2z + 2w$
