Answer:
(-6,2)
Step-by-step explanation:
[tex]x = - 6 \\ x - y = - 8[/tex]
Substitution
Substitute x = -6 from the first equation in the second equation.
[tex] - 6 - y = - 8 \\ - 6 + 8 = y \\ 2 = y[/tex]
Normally, we have to substitute either x-term or y-term in one of the equation to get another term. For this situation, we already know the value of x so It is not necessary to substitute the y-value.
Answer Check
We have to check the answer to make sure that we have got the right answer.
We can check the answer by substituting both x-value and y-value in the equation.
[tex]x - y = - 8[/tex]
Substitute x = -6 and y = 2 in the equation.
[tex] - 6 - 2 = - 8 \\ - 8 = - 8[/tex]
The equation is true. Therefore, our answer is (-6,2)
