Answer:
x=3.4 y=-5.8 (the steps are in order and I explained to the best of my ability)
Step-by-step explanation:
x+3y=-14 substitute the x for -14-3y in the second problem
x=-14-3y 2(-14-3y)-4y=30
-28-6y-4y=30
-10y=58
y=-5.8
substitute the y in the first equation for -5.8
x+3(-5.8)=-14
x-17.4=-14
x=3.4
