Question

4х – Зу = 0,
2х + Зу = 18​

Answer 1

Step-by-step explanation:

1)4x-3y=0

or,4x-y=0/3

or,x-y=0/3/4

or,x-y=0

2)2x+3y=18

or,2x+y=(-6)

or,x+y=(-3)

Answer 2

4х – Зу = 0, ......(1)

2х + Зу = 18. ........(2)

From eqn (1)

4 x - 3y = 0

4x = 3y

$x = \frac{3y}{4} \: \: \: \: \: \: ........(3)$

putting value of x in eqn (2)

$2 (\frac{3y}{4}) + 3y = 18$

$\frac{3y}{2} + 3y = 18$

$3y + 6y = 36$

$9y = 36$

$y = \frac{36}{9}$

$y = 4$

putting the value of y in eqn (3)

$x = \frac{3y}{4}$

$x = \frac{3(4)}{4}$

$x = \frac{12}{4}$

$x = 3$

Therefore, x = 3

y = 4
