Question

15n + 24 − 4(n − 3)+ 6 − 2n = 105

Answer 1

1.Distribute

1 5n+24-4(n-3(+6-2n=105

15n+24-4n+12+6-2n=105

2.Add the numbers

15n+24-4n+12+6-2n=105

15n+42-4n-2n=105

3.Combine like terms

15n+42-4n-2n=105

9n+42=105

4.Subtract  42 from both sides of equation

9n+42=105

9n+42-42=104-42

Simplify

Subtract

9n+42-42=105-42

9n=105-42

subtract again

9n=63

Divide both sides of the equation by the same term

9n=63

9n/9=63/9

Simplify

Cancel terms that are in both the numerator and denominator

9n/9=63

n=63/9

Divide the numbers

n=7

so the answer is n=7
