Solve the system of equations -8x-6y=58 and x-y=9

Step-by-step explanation:

By steps in the image:

Step 1:

To eliminate, you need one of the coefficients to be the same in both equations. We will use the term "-6x" found in the first equation.

To get this, multiply the entire second equation by 6 and simplify using the distributive property. The new equation is:

Step 2:

Now you need to subtract the first equation and the new version of the second equation. By doing this, the "-6x" in both equations will cancel each other out.

Step 3:

Solve for x in the given equation by:

Dividing both sides by -14Simplify the value of x by dividing top and bottom by 2

Step 4:

Solve for y by:

Substitute the value of x into the second equationMultiply both sides of the equation by 7Add 2 to both sides of the equationDivide both sides of the equation by -7

Solution:

:Done
