Answer:
B. (-2,1)
Step-by-step explanation:
Coincidently, I was doing my System of Equations: Word Problems HW when i saw this.
So, I'll solve using Elimination.
Convert equations into standard form: -3x + y = 7 and 2x + y = -3
Multiply first equation by -1 and arrange vertically.
2x + y = -3
3x - y = -7
----------------- <Now, Add!>
5x = -10
Divide by 5 on both sides
5x/5 = -10/5
x=-2
Plug x=-2 into any equation.
y=3(-2) + 7
y= -6 + 7
y=1
So the Point of Intersection, or solution, is (-2,1)
Hope I helped, Brainliest would be appreciated :)
Have a fantastic day!
