Answer 2

Step-by-step explanation:

1.

6+3x=15

3x=15 - 6

3x=9

x=9/3

x=3

2.

2(x+3)= 8 - 3(x-4)

2x+6= 8 - 3x + 12

2x+3x= 8+12 - 6

5x=14

x=14/5

3.

5(6-2)+1=x+1

5×4 + 1= x+1

20+1 - 1= x

20 = x

4.

3(7-2x)= 14- 8(x-1)

21-6x = 14 - 8x + 1

8x - 6x = 14 + 1 -21

2x = -6

x = -6/2

x= -3
