Question

Five times the sum of three times a number and 4 is -10, find the number.

Answer 1

N=-2

Explanation:

Step 1: Simplify both sides of the equation.

5(3n+4)=−10

(5)(3n)+(5)(4)=−10(Distribute)

15n+20=−10

Step 2: Subtract 20 from both sides.

15n+20−20=−10−20

15n=−30

Step 3: Divide both sides by 15.

15n/15=−30/15

n=−2

Answer 2

-2

Explanation:

-2*3=-6

-6+4=-2

-2*5=-10
