What is the solution of 3x + 8y = 92 and 2x - 6y = 16.

Expert Answers

An illustration of the letter 'A' in a speech bubbles

The set of linear equations 3x + 8y = 92 and 2x - 6y = 16 have to be solved.

3x + 8y = 92 ...(1)

2x - 6y = 16 ...(2)

2x - 6y = 16

=> x = 8 + 3y

Substitute in (1)

=> 3(8 + 3y) + 8y = 92

=> 24 + 9y + 8y = 92

=> 17y = 68

=> y = 4

x = 20

The solution of the given set of equations is x = 20, y = 4
