The expression -3m - [2m + (5 - m)] + 7 was simplified as 2 - 4m. without simplifying, explain how you can show that it has been simplified correctly.

Solve the like terms separately

Step-by-step explanation:

Solve the like terms separately

So, first solve m terms

-3m - 2m + m = -4m

The sign inside the square bracket changes as there is a preceding negative sign. The (5-m) bracket does not matter as you can write the expression as

-3m - [2m + 5 - m] + 7

Then we solve the non m terms

-5 + 7 = 2

So, the expression

-3m - [2m + (5 - m)] + 7 = 2 - 4m

i will u if u answer my question in math

i love jeffery and believe there is truth in tati and james' answers

step-by-step explanation:

yes i have heard the tea

i believe both

no, tati didnt over exaggerate

james might might idk and tbh dont rly care
