-y - 10 = 6x

5x + y = -10

To solve a system of linear equations by elimination, first we have to solve one of the equations for a variable and use this in the other equation

Solve the first equation for y:

-y - 10 = 6x

-10 - 6x = y

y = -6x - 10

Use this in the second equation:

5x + y = -10

5x + (-6x - 10) = -10

5x - 6x - 10 = -10

-x = -10 + 10

-x = 0

x = 0

Now that we have the value of x, we use it in the equation we solved at the beginning:

y = -6x - 10

y = -6 (0) - 10

y = 0 - 10

y = -10

Therefore the values of x and y are:

x = 0

y = 10
