S = sally C = Chris J = Joe
sally is one year older than 3 times the age of joe, so
s = 3j + 1
chris is 5 years younger than 6 times the age of jo, so
c = 6j - 5
sally and chris are the same age so
s = c so
3j + 1 = 6j - 5
-3j -3j
1 = 3j - 5
+5 +5
6 = 3j or
3j = 6
3j/3 = 6/3
j = 2

check
s = c
3(2) +1 = 6(2) - 5
6 + 1 = 12 - 5

Answer: Joe is 2 years old

Step-by-step explanation:

Let x represent the age of Joe.

Sally is 1 year older than 3 times the age of Joe. It means that the age of Sally is

3x + 1

Chirs is 5 years younger than 6 times the age of Joe. It means that the age of Chris is

6x - 5

If sally and Chris are the same age, it means that

6x - 5 = 3x + 1

6x - 3x = 1 + 5

3x = 6

x = 6/3

x = 2 years

Answer:

A) 50

B) 20

C) 20

Step-by-step explanation:

To solve the first question, we can multiply both sides by 10.

Thus, we get:

6x = 300.

Then, divide by 6, to get x:

x = 50.

You can do the same thing to all of these questions.

I've already checked the answers, but if you don't trust them, just pluck the values in.

For example, let's check the answer for question A.

0.6*50 is supposed to equal 30.

Does it equal? Yes, so we know that the answer is correct.
