Answer:
(x. y) =(4, 7)
Step-by-step explanation:
-7 x - 2 y = 14
6 x + 6 y = 18
<em>Solve the equation</em>
x = - 2/7 y
6 x + 6 y = 18
<em>Substitute the value of x</em>
6 ( - 2 - 2/7y) + 6 y = 18
<em>Solve the equation</em>
y = 7
<em>Substitute the value of y</em>
x = - 2 - 2/7 x 7
<em>Solve the equation</em>
x = - 4
<em>A possible solution is </em>
<em>(</em>x,<em> </em>y<em>) = (- 4, 7)</em>
<em>Check the solution</em>
- 7 x ( - 4) - 2 x 7 = 14
6 x ( - 4) + 6 x 7 = 18
<em>Simplify</em>
14 = 14
18 = 18
<em>The ordered pair is the solution</em>
<em>(x, y) = ( - 4, 7) </em>
<u>Boom!</u>
