Given:
olga55 [171]

Answer:

Step-by-step explanation:

y = 1/3x + 6

y = 1/4x + 3

this is just a matter of substitution...subbing in one y for the other

y = 1/3x + 6.....so sub in 1/3x + 6 in for y, back into the second equation or u can work it the other way and sub in 1/4x + 3 in for y, back into the first equation....either way will work

1/3x + 6 = 1/4x + 3

1/3x - 1/4x = 3 - 6

4/12x - 3/12x = -3

1/12x = -3

x = -3 * 12

x = - 36

now sub that back into either of ur original equations to find y

y = 1/3x + 6

y = 1/3(-36) + 6

y = - 12 + 6

y = - 6

solution is : x = -36 and y = -6 or (-36,-6)

The ratio of the number of mystery books to the number of science fiction books is 4:3. The ratio of the number of science ficti
vladimir1956 [14]

Given is the number of science fiction books = 48

Let the number of mystery books be = x

Let the number of biographies be = y

Ratio of the number of mystery books to the number of science fiction books is 4:3 so \frac{4}{3}= \frac{x}{48}

=3x=48\times4

x=64

Ratio of the number of science fiction books to the number of biographies is 4:5 so \frac{4}{5}=\frac{48}{y}

=4y=5\times48

y=60

Hence there are 48 science fiction books, 64 mystery books and 60 biographies.

So total number of books are = 48+64+60=172
