Question

Solve and find the value of x, given:  =  and x + 5y = 38
A)x = 20 
B)x = -9 
C)x = 9.02 
D)x = -17.16 
E)x = 4.33

Quizplus · Accepted Answer

The hexadecimal numbers on both sides of the equation are identical except for the 3rd digit from the right. Therefore, we can conclude that the value of that digit must be the same in both numbers. In the first number, the digit is 6 and in the second number, it is 3. The only value of x that can satisfy the equation x + 5y = 38 is x=9.02 (rounded to two decimal places) when y=5. However, none of the given answer choices match this value exactly, so the closest choice is C, which is x=9.02.
