Question

Expand the brackets and simplify
2(x + 3) + 5(x-3)

Answer 1

2(x+3) + 5(x-3)

first distribute 2 in 2(x+3)

2*x + 2*3 =2x + 6

can you do for 5(x-3) ?

Answer 2

What?????????????????/

Answer 3

\[2(x+3) = 2*x + 2*3 = 2x + 6\]
did you understand this?

Answer 4

Yes

Answer 5

5(x-3) = 5*x - 5*3

Answer 6

I kind of understand what you are trying to say but I'm a first timer at this

Answer 7

Are you a teacher

Answer 8

How long will it take for you to reply

Answer 9

ok
a(b+c) = ab+ ac
a(b-c) = ab - ac

same way
2(x+3)
here we distribute 2
2*x + 2*3 = 2x + 6

5(x-3)
here we distribute 5
5*x - 5*3
5x - 15

Answer 10

I understand now so after that what do you do

Answer 11

2(x + 3) + 5(x-3) = 2x + 6 + 5x -15
now we combine like terms

we can only add numbers with same variables.

Answer 12

So you add the x with the x and the numbers with the numbers

Answer 13

yes

2x+5x = 7x

6- 15= ?

Answer 14

-9

Answer 15

yes
so 2x + 6 + 5x -15 = 7x -9
