Answer:
[tex](-7,-7)[/tex]
Step-by-step explanation:
[tex]y=3x+14[/tex]
[tex]y=x[/tex]
Since x is equal to y we can substitute the x value in the first equation with y
[tex]y=3y+14[/tex]
Subtract both sides by y
[tex]0=2y+14[/tex]
Subtract both sides by 14
[tex]-14=2y[/tex]
Divide both sides by 2
[tex]-7=y[/tex]
And since y equals x then x will be -7 also.
(-7,-7) is the solution to this system of equations.
