Answer:
y = 9 1/3 or 8 if the first equation is 1/3x + 1/4y = 1.
Step-by-step explanation:
1/3x + 1/4y = 2
2x - 3y = -30
Multiply the first equation by -6:
- 2x - 3/2y = -12
Adding the last 2 equations:
-9/2 y = -42
y = -42 * -2/9
y = 9 1/3.
If the first equation is 1/3x + 1/4 y = 1
then y = -36 * -2/9
= 8.
