Step 1: 5 (2x + 5) = 100
Step 2: 10x + 5 = 100
Step 3: 10x= 95
Step 4: x= 9.5
What error did Andy make, and what is the correct solution to his problem?

He didn’t state the collection of like term in step 1

Step-by-step explanation:

Step 1: 5 (2x + 5) = 100

5*2x+5*5=100

10x + 25=100

Step2:Collect like term

10x = 100-25

Step 3:

10x = 75

Step 4: divide both side by 10

10x/10 = 75/10

X = 7.5

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;

answer: 1 + 1 = 11
