7(n+1)-4n=4

Distribute the 7: 7n+7-4n=4

Combine like terms (n): 3n+7=4

Subtract the 7 on both sides: 3n=-3

Divide by 3: n=-1

8=3+5(y-2)

Distribute the 5: 8=3+5y-10

Subtract: 8=-7+5y

Add the 7 to the other side: 15=5y

Divide by 5: y=3

2(x-3)+3(x-1)=-5

Distribute both terms: 2x-6+3x-3=-5

Subtract and add: 5x-9=-5

Add 9: 5x=4

Divide by 5: x=4/5

7(n+1)-4n=4

7n + 7 - 4n = 4

3n = -3

n = -1

-7(x-3)=-14

-7x + 21 = -14

-7x = -35

x=5

8=3+5(y-2)

8 = 3 + 5y - 10

15=5y

y=3

2(x-3)+3(x-1)=-5

2x -6 + 3x - 3 = -5

5x = 4

x= 4/5
