Question

equation
solve the following simultaneous equation graphically
2x+3y = 12; x - y = 2​

Answer 1

Answer:

But what is value please tell first

Answer 2

Answer:

y=5/8;

x= 11/8;

Step-by-step explanation:

equation 1:  2x+3y =12;

equation 2: x-y =2;

we will we doing it by elimination method -

first look at both the equations we can make out that if we multiply equation 2 by  2 then x can be cancelled out so just go for it

step 1: multiply equation 2 by 2:

we get,                            2x- 2y =4;                ----------------(3)

substract equation  from i.e.,

                                        2x+3y =12;

                                        - 2x+ 2y =-4;

                                ------------------------------

                                   5y = 8;

                                 => y=5/8;

put y=5/8 in eqn (2)

we get,                        => x= 11/8;
