Q:

WILL GIVE BRAINLEIST NEED TO TURN IN BY 9 P.M. PLS HURRY SUPER EASY A. What 3 consecutive even numbers added together equal 42? Use the equation n+(n+2) +(n+4)=42 to help you solveB. Give an example of an equation that has a solution of 5.

Accepted Solution

A:
Answer:A) 12,14,16B) 3x+1=16Step-by-step explanation:A)They already gave you the equation to solve:n+(n+2)+(n+4)=42n+n+2+n+4=42Put like terms together:n+n+n+2+4=42Combine the like terms:3n+6=42Subtract 6 on both sides:3n=42-6Simplify:3n=36Divide both sides by 3:n=36/3Simplify:n=12If n=12,thenn+2=14 andn+4=16.Check the addition of those numbers: 12+14+16=26+16=42.B) There is a lot of equations that have a solution of 5.It might be good start with x=5.Then just remember whatever you do to one side, you must do to the other.x=5Multiply both sides by 3:3x=15Add 1 on both sides:3x+1=16An example of equation that solution 5 is 3x+1=16.
