Answer:
and ![y=-1](https://tex.z-dn.net/?f=y%3D-1)
Step-by-step explanation:
If two equations are given, we can solve one of the equation in terms of single variable and put it in the other equation which will further give the value of x and y.
For the given equations:
Equation:1
Equation:2
Solving equation multiply equation 2 with 4 on both the sides
Equation 3
Subtracting Equation:3 from Equation:1
![8x-5y-(8x+36y)=21-(-20)\\8x-5y-8x-36y=21+20\\-41y=41\\y=-1](https://tex.z-dn.net/?f=8x-5y-%288x%2B36y%29%3D21-%28-20%29%5C%5C8x-5y-8x-36y%3D21%2B20%5C%5C-41y%3D41%5C%5Cy%3D-1)
Putting value of 'y' in Equation:2 which will give the value of x
![2x+9y=-5\\2x+9(-1)=-5\\2x-9=-5\\2x=4\\x=2](https://tex.z-dn.net/?f=2x%2B9y%3D-5%5C%5C2x%2B9%28-1%29%3D-5%5C%5C2x-9%3D-5%5C%5C2x%3D4%5C%5Cx%3D2)

Step-by-step explanation:
Find the least common denominator for each of these fractions then complete the equation until it equals 1.
Common factor is 30
u/5 = 6u/30
u/10 = 3u/30
-u/6 = -5u/30
6u/30 + 3u/30 - 5u/30 = 1
4u/30 = 1
4u = 30
u = 7.5
