Question

i have a math problem,please help...

the problem is...

"the sum of negative 14,a number,and 6 is -5.what is the number?"

they want me to write that in a equation,but its confusing.please help..

Answer 1

Just translate the words into a math expression:

the sum of (add these up)

negative 14,     (-14)

a number,      (+  x)

and 6            (+  6)

is -5.             (= -5)        

what is the number? i.e, solve for x

So your equation is:

-14 + x + 6 = -5

Add or subtract numbers to both sides to get only x on one side of the equation:

-14 +14 + x + 6 -6 = -5 +14 -6

x = -5 +14 -6

x = 3

Plug this into your original equation to make sure it works:

-14 + 3 + 6 = -5

This is correct, so you've double checked that x is equal to 3.  Hope that helps.  

Answer 2

(-14) + X + 6 = -5

x=3
