Answer:
x/7<-3
x<-21
Step-by-step explanation:
multiply the seven to get rid of x denominator
X=-1, y=1
Substitute value of y in first equation (3x+4) with y of second equation.
2x-4(3x+4)=-6
2x-12x-16=-6
-10x=10x=-1
solve for y but putting -1 for x value in either equation
y=3(-1)+4
y=-3+4
y=1
3 congruent sides
