Question

Your uncle is 2 years older than 3 times your age. When x = 2.- A. You are x years old. Write an expression to describe your uncles age. - B. You are 12 years old. How old is your uncle? There is two problems you should answer A and B

Answer 1

if you are x years old, then three times your age is x*3, or 3x. the problem then states that your uncle is 2 years older than that, so then answer leads to 3x+2. If you are 12, substitute that into the equation (x), so 3(12)+2. 3*12=36, 36+2=38. Your uncle is 38 years old if you are 12.

Answer 2

Answer:

A. The equation is y = 2 + 3x  

B.  38 years

Step-by-step explanation:

A)

From the question it says; you are x years old.

Let y be your uncles age

Then since your uncle is 2 years older than 3 times your age, the mathematical interpretation of this statement is;

y  =   2  +   3x

B)

The B part of the question states:  'you are 12 years old, how old is your uncle'?

To solve this problem, we will simply the equation in question A to solve

y = 2 +  3x

From the 'A' part of the question, your uncle' age is y and your age is x, since your age is now 12, this implies x= 12 so we substitute x= 12 in the above equation

y = 2 + 3(12)

y = 2 + 36

y = 38

Therefore your uncle's age is 38 years when you are 12 years old.
