Question

draw graphs for the equations 2x-y=3 and 3x+2y=1

Answer 1

Step by step explanation

1st equation

2x-y=3

let x=1

2*1-y=3

2-y=3

-y=3-2

-y=1

y=-1

(1,-1)

let x =2

2*2-y=3

4-y=3

-y=3-4

-y=-1

y=1

(2,1)

2nd equation

3x+2y=1

let y=2

3x+2*2=1

3x+4=1

3x=1-4

3x=-3

x=-3/3

x=-1

(-1,2)

let y =5

3x+2*5=1

3x+10=1

3x=1-10

3x=-9

x=-9/3

x=-3

(-3,5)
