Answer :
Answer:
1.25
Step-by-step explanation:
Multiply the first equation by 5 and the second equation by 4 to make the coefficients of (y) equal:
[15x + 20y = 85]
[8x - 20y = 12]
Add both equations to eliminate the (y) terms: [23x = 97] [x = \frac{97}{23} = 4]
Now, substitute the value of (x) back into the first equation:
[3x + 4y = 17]
[12 + 4y = 17]
[4y = 5] [y = \frac{5}{4} = 1.25]
