1. 7b+4(2b-x+3)
2. 3(k-4)+6k+5

Hello

Here we go

6(5x + 4) = 30x+24

2 (t-4x + 8 ) = 2t-8x+16

7(5a + 3b ) + 4 = 35a+21b +4

3 a + 4 (a-3) = 3a+4a -12 = 7a -12

6(5x + 4)

2(t-4x + 8 )

7(5a + 3b ) + 4

3 a + 4 (a-3)

Hello
Welcome to MyTutorOnline.com

3a - 5b + c + 9b + 6a + c
Collecting like terms

3a+6a -5b +9b +c +c
9a +4b+2c (as 3+6 = 9) ( 9-4=4) (1+1 =2)

9a +4b+2c Is the answer
hope this helps
