2m+3+4m+5 advice and correct solution
Hunter-Best [27]
Hey there!

On this problem, we have to combine like terms. A like term in this sense doesn't have to have the same coefficient, but it has to have the same variable.

Our like terms are 2m and 4m, along with 3 and 5.

When we add 2m and 4m we get 6m, and when we add 5 and 3 we get eight.
Notice how 5 and three are like terms because they're both whole numbers and don't have any variables.

Your solution is 6m + 8.

My advice to you is pay attention to your like terms and don't mix them up. A strategy is to underline like terms in the same color.

Hope this helps!

Find the value of two numbers if their sum is 16 and their difference is 2.4
Verdich [7]

Lets x and y are the value of two numbers.

x + y = 16

x - y = 2.4

If x + y = 16 then x = 16 - y

Substitute x = 16 - y into x - y = 2.4

16 - y - y = 2.4

16 - 2y = 2.4

2y = 13.6

 y = 6.8

x = 16 - y

x = 16 - 6.8

x = 9.2

Answer:

The value of two numbers are 9.2 and 6.8
