Question

Solve this equation -5(1+2n)=15

Answer 1

n = - 2

Explanation:

Step 1: Simplify both sides of the equation.

- 5 (1 + 2n) = 15

(− 5) (1) + (− 5) (2n) = 15

− 5 + − 10n = 15

− 10n − 5 = 15

Step 2: Add 5 to both sides.

− 10n − 5 + 5 = 15 + 5

− 10n = 20

Step 3: Divide both sides by -10.

− 10n/ − 10 = 20/ − 10

n = − 2

Hope this helps! I am sorry if it is a little confusing, I mean a lot.

Answer 2

-2

Explanation:

−5(1+2n)=15

Step 1: Simplify both sides of the equation.

−5(1+2n)=15

(−5)(1)+(−5)(2n)=15(Distribute)

−5+−10n=15

−10n−5=15

Step 2: Add 5 to both sides.

−10n−5+5=15+5

−10n=20

Step 3: Divide both sides by -10.

−10n

−10

=

20

−10

n=−2

Hope this helps!
