Question

3x - 5y =6 and 2x+3y=7​

Answer 1

ANSWER

$3x - 5y = 6$

$x = \frac{6 + 5y}{3}$

put x value in another equation

$2( \frac{6 + 5y}{3} ) + 3y = 7$

$\frac{12 + 10y}{3} + 3y = 7$

$12 + 10y + 9y = 21$

$19y = 21 - 12$

$19y = 9$

$y = \frac{9}{21}$=3/7

put y value in

$x = \frac{12 + 10 \times \frac{9}{21} }{3} = 22 \times \frac{9}{7} = \frac{198}{7}$

Answer 2

Answer:

ANSWER

put x value in equation

$----2( \frac{6 + 5y}{3} ) + 3y = 7$

$--- \frac{12 + 10y}{3} + 3y = 7$

$--12 + 10y + 9y = 21$

$---19y = 21 - 12$

$--19y = 9$

$---y = \frac{9}{21}$

put y value in

$---x = \frac{12 + 10 \times \frac{9}{21} }{3} = 22 \times \frac{9}{7} = \frac{198}{7}$
