Question

Plz solve step by step 11x-3y=12, 7x-4y=10​

Answer 1

✓ Given

» 11x - 3y = 12

» 7x - 4y = 10

✓ To find

» Values of x and y

✓ Solution

» 11x - 3y = 12 ------- ( 1 )

» 7x - 4y = 10 --------- ( 2 )

11x - 3y = 12

→ 11x = 3y + 12

$x = \frac{3y + 12}{11} \: \: \: - (3)equation$

By substituting equation (3) in equation (2) ,

$7( \frac{3y + 12}{11} ) - 4y = 10$

$\frac{21y + 84}{11} - 4y = 10$

$\frac{21y + 84 - 44y}{11} = 10$

$84 - 23y = 110$

$- 23y = 110 - 84$

$- 23y = 26$

$y = - \frac{26}{23}$

By substituting y = -26/23 in equation (1)

11x - 3y = 12

$11x - 3( - \frac{26}{23}) = 12$

$11x + \frac{78}{23} = 12$

$11x = 12 - \frac{23}{78}$

$11x = \frac{936 - 23}{78}$

$11x = \frac{913}{78}$

$x = \frac{913}{78 \times 11}$

$x = \frac{913}{858}$

$x = \frac{18}{23}$

$\therefore \: x = \frac{18}{23} \: and \: y = \frac{ - 26}{23}$
