Question

graph related problems solve graphically
3x+y=-2&x+2y=1​

Answer 1

Step-by-step explanation:

first we have to find the solutions of both the equations ....

i. 3x + y = 2

3x - 2 = -y ( we also write as)

now, put x = 0

3(0) - 2 = - y

0 - 2 = - y

y = 2 ........ (i)

now, put x = 1

3(1) - 2 = - y

3 - 2 = - y

y = -1 .......(ii)

from second equation,

x + 2y = 1

2y = 1 - x

now, put x = -1

2y = 1 - (-1)

2y = 1 + 1

2y = 2

y = 1..........(iii)

now, put x = -3

2y = 1 - (-3)

2y = 1 + 3

2y = 4

y = 2 .........(iv)

now , draw the graph of first equation and draw the line of the second equation

I hope hou can draw the graph of the two equation thank you
