Jennifer attempted to simplify the expression below.
−5●(−1.75x−1.25)+3●(−2x−1)
Her work, step by step, is shown below.
Step 1: −5●{(−1.75x+(−1.25)}+3●{(−2x+(−1)}< br />
Step 2: 8.75x+6.25+(−6x)+(−3)
Step 3: 8.75x+(−6x)+6.25+(−3)
Step 4: 2.75x+2.75
In which step did she make her first error simplifying the expression?
