In a Mathematics test, ⅕ of the students scored grade A, ⅙ of the students scored grade B and ⅕ of the remainder of students got grade C. The rest of the students either had grade D or have failed. If the number of students who failed the test was half the number of those who scored grade D, and the number of students who scored grade C is 57, what is the number of students who took the test?​

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16
