Question

Solve the equation.

5+0.5(6n+14)=3

Please explain this to me because I don't get it and feel like cheating going on Brainly.

Answer 1

Steps:

5+0.5(6n+14)=3

Multiply the bracket by 0.5 first

5+0.5(6n)+14(0.5)=3

5+3n+7=3

Add 5+7

12+3n=3

12-12+3n= 3-12

Moving 12 to the other side. Whenever moving a number to the other side the sign changes.

3n=-9

n=-3

Answer is n=-3

Answer 2

Answer:

n = - 3

Step-by-step explanation:

It's not cheating unless this question is from a quiz or test.

5+0.5(6n+14)=3                Subtract 5 from both sides.

5-5 + 0.5(6n+14) = 3 - 5   Combine

0.5(6n+14) = - 2                There are two ways to go. I prefer dividing by 0.5

0.5(6n+14)/0.5 = -2/0.5    Do the division

6n + 14 = - 4                      Subtract 14

6n+14-14= -4-14                 Combine

6n = - 18                             Divide both sides by 6

6n/6 = - 18/6                      Combine

n = - 3
