Question

Simplify by collecting like terms. - Can someone pls help me with these i dont understand. Very appreciated if you do :)

a) 3x + 5 + 2x + 1

b) 3 + 7y + 8 + y

c) 2k + 3m + 4m + 6k

d) 7u + v + v + u

e) 8n + 5 - 3n - 2

f) 4p + 7q - 3q - p

Answer 1

The answers are below. All you need to do is add the numbers with the same variable (letter) and if they do not have the same variable, then you cannot add them and leave as is.

You also need to add the numbers with no variables together.

Explanation:

a)5x+6

b) 8y+11

c) 8k+7m

d) 8u+2v

e) 5n+3

f) 3p-4q

Answer 2

a)5x+6

b) 8y+11

c) 8k+7m

d) 8u+2v

e) 5n+3

f) 3p-4q

Explanation:

3x+2x=5x 5+1=6

8+3=11 7y+y=8y (basically a 1 in front of the y so just pretend it has a 1 in front of it)

2k+6k=8k 3m+4m=7m

7u+u=8u v+v=2v (same thing like before imagine a 1 in front of all non-coefficient variables.)

8n-3n=5n 5-2=3

4p-p= 3p 7q-3q= 4q
