Multiply out then simplify:
a- 3+2(x-1)
b- 5-2(x+3)
c- 1+2(x-1)
d- 6-3(w-2)
could you show working aswell because it would help me in the future with these kind of questions.

Hello Anna
I am delighted that I can help you out with your questions
Would be so grateful if anyone can help me with these math problems?
Multiply out then simplify:
a- 3+2(x-1) = 3 +2x -2 = 2x+1 = 3
b- 5-2(x+3) = 5 -2x -6 = -1-2x = -3
c- 1+2(x-1) = 1 +2x-2 = -1+2x = 1
d- 6-3(w-2) = 6 - 3w + 6 = 12-3w = 9
God Bless You

a- 3+2x -1
b- 5 -2x -6
c- 1 +2x -2
d 6-3w +6
eg- 3 +2(x-1) you must work out the brackets to simplify 2 x X & 2 x -1 = 3 + 2x -1

3+2(x-1) = 3 + 2x - 2 = 1 + 2x
5-2(x+3) = 5 - 2x + 6 = 11 - 2x
1+2(x-1) = 1 + 2x - 2 = -1 + 2x
6-3(w-2) = 6 - 3w - 6 = 0 - 3w = -3w

I'll do one to show you how it's done.
6-3(W-2)
3(W-2) means you muliply each term in the ()'s by the number outside of it so:
3(W-2) gets turned into 3W + 6
Now you have the problem
6-3W + 6
Combine like terms so what is 6 +6? 12 right? So you end up with -3W + 12

I don't understand what you are asking for !!!
are these equations where you are asked to find the value of x? if so, then you must show the other side.
If you are only asking to make it look simple, then let me try a
3 + 2(x-1)
3 + (2x - 2) simply it becomes
3 + 2x - 2
1 + 2x
and for the rest
b - 1 + 2x
c - 2x - 1
d - 12 - 3w
I hope i got your point
goodluck

a- 3+2(x-1) = 3+2x-2 = 2x+1
b- 5-2(x+3) = 5-2x-6 = -2x-1
c- 1+2(x-1) = 1+2x-2 = 2x-1
d- 6-3(w-2) = 6-3w+6 = 12-3w

a) =3+2x-2
=1+2x
2x=-1 so x= -1/2
b) = 5-2x-6
= 5-6-2x
= -1-2x
-2x=1 so x=1/2
c) = 1+2x-2
= -1+2x
2x=1 so x= -1/2
d) =6-3w+6
=-3w so w=3

you work out the sum, then add the backet
so a)3+2(x-1)=5+x-1
=4+x

i will do one,
3+2(x-1)
3+2x-2<---- distribute you 2 by multiplying all things in the () by 2
1+2x <--- combine like terms..bam your done
