Answer:
Step-by-step explanation:
It is easier to solve it by elimination.
<u>Add the first equation to 4 times the second one to eliminate y:</u>
- 1/4x + 4/5y + 4*5/16x - 4/5y = 3 + 4*5
- 1/4x + 5/4x = 3 + 20
- 6/4x = 23
- 3/2x = 23
- x = 2*23/3
- x = 46/3
<u>Now find y:</u>
- 1/4*46/3 + 4/5y = 3
- 23/6 + 4/5y = 3
- 4/5y = 3 - 23/6
- 4/5y = -5/6
- y = -25/24
