Y=2 by the method of substitution (x is 7).
Answer:
a
the first answer
Step-by-step explanation:
5 + 6 − 1 2 − 1 1 -11y 5+6y−12−11y − 7 + 6 − 1 1
− 7 + 6 − 1 1 −7+6y−11y − 7 − 5
− 7 − 5 −7−5y − 5 − 7
Solution: −5y−7
Given:
and
.
To find:
The relationship between the ratios.
Solution:
We have, two ratios in the fraction form.
and 
First ratio = 
= 
=
(Cancel out the common factors)
First ratio = Second ratio
Since, the both ratios are equal to each other, therefore, the given ratios are equivalent ratios.
