Answer: −12y+30z
Step-by-step explanation:
5(-3y+3z)-3(-5z-y) Expand by distributing terms.
−15y+15z−3(−5z−y) Expand by distributing terms.
−15y+15z−(−15z−3y) Remove Parentheses
−15y+15z+15z+3y Collect like terms & Simplify
(−15y+3y)+(15z+15z)
=−12y+30z
Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! :-)
