We are going to solve this problem without using algebra. However, we will use the concept of substitution.
Look at the two equations.
Now we substitute one of the yellow apples with the red apple.
Repeat with the other yellow apple.
So now we have only red apples.
Let's rearrange things a bit.
Now we compare both sides of the equation.
Cancel the apples when you find them.
Getting nearer to the solution ......
Ah ha! We've found the value of the red apple!
Now we plug this value back into one of the equations.
And we have the final answer!
