Question

is (2, 6) a solution to this system of equations?
2x - 2y = -8
19x - 7y = -4
yes
no

Explanation:

Step1: Substitute into first - equation

Substitute \(x = 2\) and \(y=6\) into \(2x - 2y=-8\).
\[2\times2-2\times6=4 - 12=-8\]

Step2: Substitute into second - equation

Substitute \(x = 2\) and \(y = 6\) into \(19x-7y=-4\).
\[19\times2-7\times6=38 - 42=-4\]

Answer:

yes
