The value of x and y are 5/6 and 8/5 respectively
Given the systems of equations
- 12x + 15y = 34 ...................... 1 *1
- -6x + 5y = 3 ..................... 2 * 3
Solving the equations using the
elimination method
12x + 15y = 34
-18x + 15y = 9
Subtract both expressions:
12x-(18x) = 34 - 9
12x+18x = 25
30x = 25
x = 5/6
Substitute x = 5/6 into equation 1 to have:
12x + 15y = 34
12(5/6) + 15y = 34
10 + 15y = 34
15y = 24
y = 8/5
Hence the value of x and y are 5/6 and 8/5 respectively
