Answer:
-6x+12
-9+5a
7x+63
8y-4/5x-12
Step-by-step explanation:
To solve these all you have to do is take the number outside of the parenthesis and multiply them by each term.
-3(2x)-3(-4) All I did here was expand the problem to show what i mean by terms.
-6x+12
Do this for each problem.
0.1(-90)+0.1(50a)
-9+5a
-7(-x)-7(-9) For this one you are taking negatives times negatives so each answer will be positive.
7x+63
4/5(10y)+4/5(-x)+4/5(-15)
8y-4/5x-12

The two expressions are not equal
A rule of thumb in these type of equations (at least, for me, personally) is to bracket off the like term. We’ve got 3 things here, so we gotta bracket them.
(5)+(10s-8s)
So now, we’ve got them separated. Next, we perform our given function. In this case, we subtract 8 from 10, leaving us with 2.
(5)+(2s)
As we no longer have any like terms, to be simplified or otherwise, we open the brackets:
5+2s
And you’ve obtained your answer!
Answer= 5+2s
