Question

Find the solution of this system of equations. Separate the x and y values with a comma.

x-2y=19
x-y=-5

Answer 1

-13,-8 is incorrect

Explanation:

Answer 2

Ok so in solving systems of linear equations, we first find the value of a variable. By looking at the equations, solving for x by using the second equation seems the easiest.

x - y = -5

x = -5 + y

x = y - 5

Then we plug in the equation of x into the first equation and solve for y.

x - 2y = 19

y - 5 - 2y = 19

-3y - 5 = 19

-3y = 24

-y = 8

y = -8

Now we plug in y = -8 in the solved equation for x

x = y - 5

x = -8 - 5

x = - 13

Therefore, x = -13 and y = -8

Hope this helps!
