Question

Solve the simultaneous equations
2x + 3y = 8
5x + 2y = 9

Answer 1

Answer :-

___________________________________

$2x + 3y = 8 -----(1) \times2 \\ 5x + 2y = 9 - - - - - (2) \times 3 \\ (1) - (2) \\ - 11x = - 11 \\ \implies \: x = 1 \\ \implies \: y = 2$

Answer 2

Step-by-step explanation:

Subtract EQn1 from EQn2

5x +2y =9

- 2x +3y =8

(-) (-) (-)

===================

3x -y =1

===================

So,y =3x-1

put value of y in EQn 1

2x+3(3x-1)=8

2x+9x-9=8

11x=17

x =17/11

So,y=3*17/11-1

y= 51/11-11/11

y= 40/11
