An apple contains 90 calories and 5 g of fiber. A banana contains 105 calories and 4 g of fiber. Set up a system of equations that could be solved to determine the number of apples (A) and bananas (B) that should be eaten to obtain 2415 calories and 114 g of fiber.

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
