2x + y = 3 2x – y = 4 Using elimination to solve this system results in the equation .
DanielleElmas [232]
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

(5,-5) and y = 3/2x +3Whats the equation of the line in slope intercept form
statuscvo [17]

Step-by-step explanation:

let (5,-5) =(x1,y1)

from eqn y=3/2x+3

slope (m)=3/2

now,

eqn in slope intercept form is;

(y-y1)=m (x-x1)

  • (y-5)=3/2 (x+5)
  • 2 (y-5)=3 (x+5)
  • 2y-10=3x+15
  • 3x-2y+25=0 is required eqn
