The correct form of expression after solving the errors is :
-5.83b + 24
Given Margie's work for adding linear expressions are:
the expression is (−1.56b + 10) − (4.27b − 14)
step 1: −1.56b + 10 + (−4.27b) + 14
In the first step of margie, she did not used the proper method of opening the brackets.
The negative sign is used to multiply the terms inside the brackets.
so the correct step is:
step 1: -1.56b + 10 - 4.27b + 14
in the next step arrange the variables and constants.
step 2 : -1.56b - 4.27b +10 + 14
next add the variables and the constants:
step 3: (-1.56b - 4.27b) +(10 + 14)
step 4: -5.83b + 24
Hence we get the required results.
