Girardo is using the model below to solve the equation 3 x + 1 = 4 x + (negative 4).
3 long green tiles and 1 green square tile = 4 long green tiles and 4 red square tiles
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 Negative x = negative 5
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.
