Using cramer’s rule, what is the value of y in the system of linear equations below? 2x-y=3 5x-2y=8

The value of y is 1

Step-by-step explanation:

Given the system of linear equations

2x-y=3

5x-2y=8

we have to find the value of y using cramer’s rule

Cramer’s Rule is a method that uses determinants to solve the systems of equations that have same number of equations as that of variables.

The coefficient matrix is

For Y-matrix

By cramer's rule

Hence, value of y is 1

what is the original number? you forgot to add it.

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
