Which expression represents the following situation? multiply the sum of a number and 3 by the difference of 8 and a number

(x + 3)*(8-y)

Step-by-step explanation:

The first step to solve this question is interpreting it.

The first keyword is multiply

It means that we are going to multiply two terms.

Sum of a number and 3.

We do not know the number, so i am going to call it x.

So (x + 3)

The difference of 8 and a number

Another number that we do not know, and it does not say that these numbers are equal, so i am going to call this number y.

So (8-y)

Multiplying

(x + 3)*(8-y)

9

Step-by-step explanation:

2(m+2) = 22

Using the distributive property, you can multiply the 2 to both the "m" term and the "2".

2m + 2*2 = 22

2m + 4 = 22

Then you isolate the variable and solve.

2m = 22 - 4

2m = 18

m = 9
