Answer:

Step-by-step explanation:

3(n+1)=2(n+4)

3 × n + 3 × 1 = 2 × n + 2 × 4

3n + 3 = 2n + 8

3n - 2n = 8 - 3 we regroup by categories (unknown and number)

n = 5

kherson [118]

Answer:

x= -19

Step-by-step explanation:

3-(x-3)=25

Distributive property to cancel out the paranthesis

3-x+3=25

Add the number

6-x=25
