Question 54398
1st:3x/2 + y/4=7
Multiply thru by 4 to get:
2nd: 6x+y=28
3rd: x/5 - 2y/3 = 2 1/3
Multiply thru by 15 to get:
4th: 3x-19y=35
To eliminate the "x" terms multiply thru 4th by 2 to get:
5th: 6x-38y=70
Subtract 5th from 2nd to get:
6th: 39y=-42
Then y=-14/13
Substitute that into 2nd to solve for "x":
6x-14/13 = 28
6x=14/13 + 364/13
6x = 378/13
x= 63/13
Solution:
x=63/13 y=-14/13
