Answer:
The solution is the point (-2,-2)
Step-by-step explanation:
we have
[tex]y=x[/tex] ----> equation A
[tex]y=-6x-14[/tex] ----> equation B
Solve the system by substitution
substitute equation A in equation B
[tex]x=-6x-14[/tex]
Solve for x
[tex]6x+x=-14\\7x=-14\\x=-2[/tex]
Find the value of y
substitute the value of x in the equation A
[tex]y=x[/tex]
so
[tex]y=-2[/tex]
therefore
The solution is the point (-2,-2)
