Answer: 6.
Step-by-step explanation:
4^2 = 16
10 − 16 + 6 * 2
6 * 2 = 12
10 − 16 + 12
10 - 16 = -6
-6 + 12 = 6
For this case, the first thing we must do is define variables.
We have then:
x: number of years of Joan y: number of years of ellen We now write the system of equations:
Solving the system we have:
So that Joan is 21 years old then:
