The value of y in the expression 4x + 23 = 9x -3821y -1 is (5x -25)/3821 .
An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e. a and b respectively, are not equal to zero.
According to the given question
We have a linear equation in two variables
4x + 23 = 9x -3821y -1
For finding the value of y solve the above equation by adding and subtracting the like terms.
So, 4x + 23 = 9x - 3821y -1
⇒ 23 = 9x -4x -3821y -1 (subtracting 4x from both the sides)
⇒ 23 + 1 = 5x -3821y (adding 1 both the sides)
⇒ 25 = 5x - 3821y
⇒ 3821y = 5x -25
⇒ y = (5x -25)/3821
Hence, the value of y in the expression 4x + 23 = 9x -3821y -1 is (5x -25)/3821 .
