Four less than nine times a number is one hundred twenty-two. Find the original number.

Mathematics

Answer:

The number is 14

Step-by-step explanation:

Denote the original number by z. The expression "Four less than nine times a number is one hundred twenty-two" can be rewritten in an equation.

Our number is z, then the left hand side of the equation is 9z-4.

The right side of the equation is 122. Then the complete equation is 9z-4=122. Add 4 in both sides to get 9z=122+4=126. Now, divide by 9 in both sides to get z=\frac{126}{9}=14

larisa [96]
Y+x=98
y-x=22

I'm going to use elimination. 

y+x=98
y-x=22
-----------
2y+0x=120 SIMPLIFY 2y=120 SIMPLIFY y=60. 

Substitute that into either equation and you get y=60 and x=38
