First, write both the equations in its standard form.

Now, write the equations in form of matrix.

Then, multiply the equation towards the left by using the inverse of matrix 

The product of the matrix & its inverse will be the identity matrix.

Now, multiply the matrices that lie on the left-hand side of the equal sign.

For the 2 × 2 matrix
, the inverse matrix is ⇨
.

Do the calculations.

Multiply the matrices.

Do the arithmetics again.

Finally, extract the matrix elements x & y & write them separately.

Jared begins with $18
If he spends $3.87 then you subtract that from the $18 which leaves Jared with $14.13. If Jared spends $5.95 then you subtract that from $14.13 which leaves Jared with $8.18. This means Jared spent $8.18 on the magazine.
