Question

solve the simultaneous equations by graphical method 3x -y=7; x+4y=11

Answer 1

3x-y=7
x+4y=11
3 (x+4y=11)
by solving the x and y terms we get
y =2
by substutng y value in any eqn we get
x=3

Answer 2

Answer:

(3,2)

Step-by-step explanation:

Given : $3x -y=7$

           $x+4y=11$

To Find : solve the simultaneous equations by graphical method

Solution:

Blue line shows     $3x -y=7$

Green line shows    $x+4y=11$

Thus the solution of the given system of equations is (3,2)
