22x - y = -23

Question

Consider this system of linear equations:

22x − y = -23 (equation 1)

11x + 12y = 1 (equation 2)

To find the value of x, you need to substitute in equation 2.
The value of x is .

Answer 1

From the first equation,

 

y = 22x + 23

 

 

Substitute this value of y in the second equation.

 

11x + 12(22x + 23) = 1

 

 

Solve for x from this equation.
