Solve equation 3(n - 5) = 7 - 2(n + 1)

n= 4

Step-by-step explanation:

3 multiplied by n is 3n.

3 multiplied by -5 is -15.

so 3n-15= 7-2(n+1)

7-2(n+1) is -2 multiplied by n is -2n and -2 multiplied by 1 is -2.

3n-15=7-2n-2

then move the variables to one side and numbers to the one side.

3n+2n=15+7-2

*If you are moving across the equation the symbols change. Like negative to positive. Division to multiplication.

so 5n=22-2

5n=20

5 multiplied by 4 is 20 so n is going to be 4.

N=4

n = 4 4/5

or, in decimal form:

n = 4.8

Step-by-step explanation:

3n - 15 = 7 - 2n + 2

3n + 2n = 7 + 2 + 15

5n = 24

n = 4 4/5

n = 4.8
