1.
2x=3(1-x)-(x+1)
2x = 3-3x-x-1
2x+3x+x = 3-1
6x = 2
x = 2/6
x = 1/3

2.
-2(y-3)=-3(6-2y)
-2y+6 = -18+6y
6+18 = 6y+2y
24 = 8y
y = 24/8
y = 3

3.
2(z+1)=3(z-4)
2z+2 = 3z-12
2+12 = 3z-2z
z = 14

4.
2(8n-10)=9n+8
16n-20 = 9n+8
16n-9n = 8+20
7n = 28
n =28/7
n = 4

1. 2x = 3(1-x)-(x+1)
2x = 3-3x-x-1
2x = 2-4x
6x = 2
x = 1/3

2. -2(y-3) = -3(6-2y)
-2y+6 = -18+6y
24 = 8y
3 = y

3. 2(z+1) = 3(z-4)
2z + 2 = 3z - 12
14 = z

4. 2(8n-10) = 9n+8
16n -20 = 9n +8
7n = 28
