Question

2a+3b=5

b=a-5 (answer choices)

1.a=6, b=1 2. a=4, b=1


3. a=4,b=-1 4. a=6, b=-1

Answer 1

The answer would be 3.

Explanation:

If we plugged in a=4 and b=-1 into the equation 2a+3b=5, we would get 2(4)+3(-1)=5. 2x4 is equal to 8 and 3x-1 is equal to -3. 8+-3 or 8-3 is equal to 5. I hope this helps! :)
