To solve, set the equations equal to each other, so 4(2t-1)=2(3t+1). Next, distribute your 4 and 2, getting 8t-4=6t+2. Now, solve for t. 8t-4=6t+2, subtract 6t from both sides, 2t-4=2, add 4 to both sides, 2t=6, and divide 2, t=3. Now that you have your value of t, plug it into either equation, 4(2(3)-1)=4(6-1)=4(5)=20. This means they each picked 20 apples.
