Answer 2

Step-by-step explanation:

Solution:-

$3y = x - 2..........(1)$

And,

$2x + 5y = 15.........(2)$

NOW,

chose Equation (1)

$3y = x - 2$

$= > y = \frac{x - 2}{3} .........(3)$

Puting y value in Equation ( 2)

$2x + 5y = 15$

$= > 2x + 5 \times \frac{x - 2}{3} = 15$

$= > 2x + \frac{5x - 10}{3} = 15$

$= > \frac{6x + 5x - 10}{3} = 15$

$= > 11x - 10 = 45$

$= > 11x = 45 + 10$

$= > x = \frac{55}{11}$

$= > x = 5$

Puting x value in Equation (3)

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

$= > y = \frac{5 - 2}{3}$

$= > y = \frac{3}{3}$

$= > y = 1$

so, we find

x = 5

y= 1
