Question

2y - x = 0 ; 10x + 15y = 105​

Answer 1

$2y - x = 0 \\ 2y = x$
$10x + 15y = 105 \\ 10(2y) + 15y = 105 \\ 20y + 15y = 105 \\ 35y = 105 \\ y = 3$
$2y = x \\ 2 \times 3 = x \\ 6 = x$

Answer 2

Answer:

x=6 y=3

Step-by-step explanation:

2y-x=o......1

10x+15y=105.....2

from 1

2y =x

y=x/2

putting the value of y in 2

10x+15(x/2)=105

10x+15x/2=105

20x+15x=210

35x=210

x=6

then y=x/2

so y=6/2

y=3
