5x-3y=16
3x-5y=-4
Multiply the first equation by 3; the second one by 5
15x-9y=48
15x-25y=-20
Eq 1 - Eq 2:
-9y+25y=48+20=68
16y=68
4y=17
y=17/4
5x-3y=16
5x-3×17/4=16
5x=16+51/4=(64+51)/4=115/4
x=115/4/5=23/4
x=23/4
Answer:
The multiplier is 1
specifically:
![\frac{6}{6}](https://tex.z-dn.net/?f=%20%5Cfrac%7B6%7D%7B6%7D%20)
Step-by-step explanation:
Let the multiplier be k
Then,
![\frac{5}{7} \times k = \frac{30}{42}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5%7D%7B7%7D%20%20%5Ctimes%20k%20%3D%20%20%5Cfrac%7B30%7D%7B42%7D%20)
We multiply both sides by 7/5
![\frac{7}{5} \times \frac{5}{7} k = \frac{30}{42} \times \frac{7}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B7%7D%7B5%7D%20%20%5Ctimes%20%20%5Cfrac%7B5%7D%7B7%7D%20k%20%3D%20%20%5Cfrac%7B30%7D%7B42%7D%20%20%5Ctimes%20%20%5Cfrac%7B7%7D%7B5%7D%20)
![k = \frac{6}{6}](https://tex.z-dn.net/?f=k%20%3D%20%20%5Cfrac%7B6%7D%7B6%7D%20)
We can simplify this further to get 1.
This implies that:
![\frac{5}{7} \times \frac{6}{6} = \frac{30}{42}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B7%7D%20%20%5Ctimes%20%20%5Cfrac%7B6%7D%7B6%7D%20%3D%20%20%5Cfrac%7B30%7D%7B42%7D%20)
Hence the multiplier is 1.
