Question 410820
7x-6y=-80
5x+67=y

first you are going to put the second equation into y= format: y=5x+67
now plug in 5x+67 for y in the first equation

7x-6(5x+67)= -80 distribute the 6
7x-30x-402= -80 combine like terms

7x-30x= -23x

-23x-402= -80 get x by itself, divide both sides by -23
x=-14
Plug in -14 in for x in the first equation

y=  5(-14)+67
     -70+67 
   y = -3

to check plug both x and y in first equation
-3=5(-14)+67 
-3=-70+67
-3= -3 true

your point is (-14, -3)
hope this helps
