To solve the system of equations using the elimination method, let's carefully extract the equations from the image and then solve them step by step.

The system of equations extracted from the image is:

$9x - 15y = 42$ $10x + 15y = 57$

Step 1: Add the Equations

To eliminate $y$, we'll add both equations together:

$(9x - 15y) + (10x + 15y) = 42 + 57$

Simplify:

$9x + 10x = 99$ $19x = 99$

Step 2: Solve for $x$

Now, divide both sides by 19:

$x = \frac{99}{19}$ $x = 5.21 \, (\text{approximately})$

Step 3: Substitute $x$ into one of the original equations

Next, substitute $x = 5.21$ back into one of the original equations to solve for $y$. We can use the first equation:

$9(5.21) - 15y = 42$ $46.89 - 15y = 42$

Step 4: Solve for $y$

Now, subtract 46.89 from both sides:

$-15y = 42 - 46.89$ $-15y = -4.89$

Finally, divide by -15:

$y = \frac{-4.89}{-15}$ $y = 0.33 \, (\text{approximately})$

Solution

The approximate solution to the system of equations is: $x \approx 5.21, \quad y \approx 0.33$
