Convert liters to milliliters so that you have one unit for all of the amounts in the question.
1 liter is equal to 1000 milliliters, so multiply the 1.5 liters you have by 1000:
Since you drank 295 milliliters, and your friend drank 135 milliliters, you will subtract those values from the amount in the bottle:
There is 1070 milliliters of water left in the bottle.
If you want to find the amount remaining in the bottle in liters, divide the amount remaining by 1000 to convert milliliters to liters:
Converted back into liters, there is 1.07 liters of water left in the bottle.

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.
