Substitute the valus of x and see which answer fits.
for x=0, y = 4·0 - 3 = -3
for x=1, y = 4·1 -3 = 1
Only the 2nd choice matches:
Input x 0 1 2 Output y -3 1 5
Im pretty sure is teh 3rd one

Step-by-step explanation:
4x+2=7x-25
subtract for on both sides

27=3x
Then divide 3 on both sides
x=9
Answer: 9 boys remained in the choir.
Step-by-step explanation:
Let x be the number of of boys and y be the number of girls.
In a school choir, 1/2(half) of the members were girls.
i.e (1)
At the end of the year, 3 boys left the choir, and the ratio of boys to girls became 3:4.
Put y= x from (1), we get
Thus , the number of boys : x= 12
Boys remained in the choir = 12-3=9
