Question

solve the following simultaneous equation 7x+8y=9;x-2y=0

Answer 1

Heya folk !!

Here's the answer you are looking for

We have two equations;

1️⃣ 7x+8y=9

2️⃣ x-2y=0

From equation 2️⃣,

x - 2y = 0

➡️ x = 2y

Put this value of x in equation 1️⃣,

7x + 8y = 9

7 (2y) + 8y = 9

14y + 8y = 9

22y = 9

$y = \frac{9}{22}$


$x = 2y = 2( \frac{9}{22} ) = \frac{9}{11}$

$Therefore, \: x = \frac{9}{11} \: and \: y = \frac{9}{22}$
