When the first equation is multiplied by -3, the sum of the two equation
and any of the original equations will have the same solution as the
original equations. Hence 5x = -10 and 11x - 9x = -13 will have a
solution of (-2, -1).
Answer:
145
.8x = 116 (80% of class is 116)
x=145

Step-by-step explanation:
In this question it is already given that a person travels 8 miles in 0.5 hours. This is enough information to get to the required answer. Let us first write down all the information's that are already given in the question.
In 0.5 hours the person covers a distance = 8 miles
Then
