<h3>x is 2 and y is -2</h3>
<em><u>Solution:</u></em>
Given that,
3x-2 equal x-y equals 4
Which means,
3x - 2 = x - y = 4
Therefore,
x - y = 4
Also,
3x - 2 = 4
Simplify above expression
3x - 2 = 4
3x = 4 + 2
3x = 6
Divide both sides by 3
x = 2
Substitute x = 2 in x - y = 4
2 - y = 4
y = 2 - 4
y = -2
Thus x is 2 and y is -2

Answer:
Number of bacteria after 36 hour (A) = 381 (Approx)
Step-by-step explanation:
Given:
Number of bacteria (p) = 2,000
Total time (n) = 36 hours
Decay rate = 4.5 % = 0.045 per hour
Find:
Number of bacteria after 36 hour (A)
Computation:

Number of bacteria after 36 hour (A) = 2,000[1-0.045]³⁶
Number of bacteria after 36 hour (A) = 2,000[0.955]³⁶
Number of bacteria after 36 hour (A) = 2,000[0.190599333]
Number of bacteria after 36 hour (A) = 381.19866
Number of bacteria after 36 hour (A) = 381 (Approx)
