Question

Simplify the following expression.

3y – 2x + z – 2x + 3(x + y)
A.
–x + 4y + z
B.
–x + 6y + z
C.
x + 4y + z
D.
3x + 4y + z

Answer 1

\[\LARGE 3y-2x+z-2x+3x+3y\]
can you continue ?

Answer 2

yes

Answer 3

:)

Answer 4

i can't do it :( i don't get it?

Answer 5

Group the like terms,ie terms with same variable
For instance,
you can see there are 3 terms with 'x' -> -2x-2x+3x
Simplify it, then you'll get (-2-2+3)x = -x
Can you do the rest now?

Answer 6

3y−2x+z−2x+3x+3y
(3y+3y)=6y
(-2x-2x+3x)=-x
z
Put it all back together
6y-x+z

Answer 7

You break it into parts
