Hello!
We can solve this by using substitution
we can plug y = x - 1 into the other equation
So 2x - 3( x - 1) = -1
We can distribute the -3 to (x - 1)
2x - 3x + 3 = -1
Combine like terms
-x + 3 = -1
Subtract 3 from both sides
-x = -4
Since x is negative we can multiply both sides by -1
x = 4
We can plug x into the first equation
y = (4) - 1
y = 3
The answers are x = 4 and y = 3
Hope this helps!

Answer:
y = 5 * (3^x)
Step-by-step explanation:A scientist begins an experiment with a culture of 5 bacteria cells.
Every hour, the number of bacteria cells triples.
Which equation can be used to represent the number of bacteria cells, y, as it relates to time in hours, x?
:
I think it would be y = 5 * (3^x)
