Question

find value of x and y: 3x + 2y = 6 , 9x + 6y = 18​

Answer 1

Answer:

$3x + 2y = 6 \\ 2y = 6 - 3x \\ y = \frac{6 - 3x}{2}$

THE VALUE OF Y IS

PUT THE VALUE OF Y IN EQUATION 2

$9x + ( \frac{6 - 3x}{2} ) = 18 \\ \frac{18x + 6 - 3x}{2} = 18 \\ 15x + 6 = 32 \\ 15x = 24 \\ x = \frac{24}{15} \\ x = \frac{8}{5}$

PUT THE VALUE OF X IN EQUATION 3
