2x + y = 3 2x – y = 4 Using elimination to solve this system results in the equation .
2 answers:
You can use elimination by adding the two equations to "cancel out" one of the variables. in this example y will cancel out.
2x + y = 3
+
2x - y = 4
________
2x = 6
x = 3
now that we know our x value, we can plug it into one of the other equations to get our y value.
2(3) + y = 3
6 + y = 3
y = -3
your answer for this system is x=3, y=-3

Answer: A: 6
B: 4
C: 2
Step-by-step explanation:
Step-by-step explanation:
If A=650+135N; and B=585N,
then A+B= 650+135N+585N=650+620N
T=720N+650
6--3=9
15-6=9,
so
24+9=33,
33+9=42,
42+9=51
33,42,51
