Question

elimination method 3x+2y=11 and 5x-2y=13​

Answer 1

Step-by-step explanation:

add (I) eqn and (ii)

$3x+2y=11 \\ 5x - 2y = 13$

$8x = 24 \\ x = \frac{24}{8 } \\ x = 3$

putting the value of x in (I) equation

$3x + 2y = 11 \\ 3(3) + 2y = 11 \\ 9 + 2y = 11 \\ y = \frac{11 - 9}{2} \\ y = \frac{2}{2} \\ y = 1$
