Answer
$(1,-\displaystyle \frac{1}{19})$
Work Step by Step
The equations are in standard form. The coefficients of y are $\pm 19$,
which makes y easy to eliminate by adding ... we use the elimination method.
Add the equations:
$ 20x=20\qquad$ ... and solve for x
$x=1$
Now, back-substitute into one of the initial equations
$8x+19y=7$
$8(1)+19y=7$
$ 8+y=7\qquad$ ... subtract 8
$ 19y=-1\qquad$ ... divide with 19
$y=-\displaystyle \frac{1}{19}$
Form an ordered pair $(x,y) $ as the solution to the system
$(1,-\displaystyle \frac{1}{19})$
