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

x = -1.

Explanation:

From equation 1:

y = 22x + 23

Plug this into equation 2:

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

11x + 264x + 276 = 1

275x = -275

x = -1
