2).3).4).5).n = 6-1.2.......
1. 5(a-2)-3a+48
2. 2(3n+1)+4n+5=87
3. 5w=63-2w
4. 6p-9=2p+19
5. 2(n+3)=5n-12

a = 29 n=8 w =9 p=7 n =6

1).
5(a - 2) - 3a + 48
= 5a - 10 - 3a + 48
= 2a + 38
= 2(a + 19)

2).
2(3n + 1) + 4n + 5 = 87
6n + 2 + 4n + 5 = 87
10n = 80
n = 8

3).
5w = 63 - 2w
7w = 63
w = 9

4).
6p - 9 = 2p + 19
6p - 2p = 19+ 9
4p = 28
p = 7

5).
2(n + 3) = 5n - 12
2n + 6 = 5n - 12
3n = 18
n = 6

1. 5(a-2)-3a+48=5a-10-3a+48
=2a+38
2. 2(3n+1)+4n+5=87
6n+2+4n+5=87
10n=80
n=8
3. 5w=63-2w
7w=63
w=9
4. 6p-9=2p+19
4p=28
p=7

5. 2(n+3)=5n-12
2n+6 =5n-12
3n=18
n=6

1. 5a-10-3a+48= 2a+38
2. 6n+2+4n+5=87 10n+7=87 10n=80 n=8
3. 7w=63 w=9
4. 4p-9=19 4p=28 p=7
5. 2n+6=5n-12 6=3n-12 18=3n n=6

1.2a+38
2.n=8
3.w=9
4.p=7
5.n=6
i'm preety sure a is supposed to be 29 though because you made the equal sign to addition

ummmmmmmmm im rlllllllllllyyy sry i cant do this...im only 7 but i rllly need the points? so cood u PLEASE choose me as best answer thn i will ask my mom 2 solve these for u?

How about 2 points for one:

5) 2n + 6 = 5n - 12
3n = 18
n = 6
