What is the Answer to these Algebraic questions and how did you get it ???

Question

This is Simplifying Algebraic Expressions.

187) 4m + 3d - 5m + d

188) t - 3 + 2 (t + 2)

You may use any property to answer it, but make sure to show your

work. :) Thank you !

Answer 1

group all like terms, meaning group the m's and the d's in the first one

4m+3d-5m+d->

4m-5m +3d+d=

-m +4d

t-3 +2(t+2) ->

t-3+2t+4 =

3t+1

Answer 2

187) 4m + 3d - 5m + d

4m - 5m plus 3d plus d.

-m + 4d.

188) t - 3 + 2 (t + 2)

t - 3 + 2t + 4  (multiply the 2 into the brackets)

t + 2t - s +4

3t - 3 + 4

3t + 1
