Too add mixed numbers, first convert them to improper fractions:
34/5 + 53/10
Next, find a common denominator, which in this case is 10.
Convert 34/5 so that it has a denominator of 10 by multiplying the ENTIRE fraction by 2: 68/10
68/10 + 53/10 = 121/10
You can either give your answer in the form of an improper fraction: 121/10, or a mixed number 12 1/10
![4x - y = - 5 \\ - 2x + y = 3](https://tex.z-dn.net/?f=4x%20%20-%20y%20%3D%20%20-%205%20%5C%5C%20%20-%202x%20%2B%20y%20%3D%203)
Solve the second equation for y
![4x - y = - 5 \\ y = 3 + 2x](https://tex.z-dn.net/?f=4x%20-%20y%20%3D%20%20-%205%20%5C%5C%20y%20%3D%203%20%2B%202x)
Substitute the given value of y into the first equation
![4x - (3 + 2x) = - 5](https://tex.z-dn.net/?f=4x%20-%20%283%20%2B%202x%29%20%3D%20%20-%205)
Solve the equation for x
![x = - 1](https://tex.z-dn.net/?f=x%20%3D%20%20-%201)
Substitute the given value of x into the second equation
![y = 3 + 2( - 1)](https://tex.z-dn.net/?f=y%20%3D%203%20%2B%202%28%20-%201%29)
Solve the equation for y
![y = 1](https://tex.z-dn.net/?f=y%20%3D%201)
The possible solution of the system is the ordered pair (x,y)
![(x,y) = ( - 1, 1)](https://tex.z-dn.net/?f=%20%28x%2Cy%29%20%3D%20%28%20-%201%2C%201%29)
