Answer:
proportional, k = -7/8
Step-by-step explanation:
since y=kx, k must be -7/8
1. Rename the mixed numbers with common denominators
2. Add the mixed numbers together to get 15 4/6
3. Subtract the sum from 26 to get 10 1/2
4. Since the only term left on the left is k so k=10 1/2
The answer is gonna be 14:36
ans is b...multiply first eqn by -2
=》 -6x -4y = -48...eqn 3
add eqn 2 and 3...
=》 -2y = -18
=》 y = 9...x =2
