Question

solve:::::
5x+3y=9;3x-3y=12​

Answer 1

Answer:

y = 15/ -6 is the answer

Step-by-step explanation:

do the eliminaion method.....

5x+3y=9  ---------------------------- (1)

3x-3y=12​  --------------------------- (2)

                     (-)

-------------

8x+0=12

-------------

now,

8x+0=12

8x=12

$x=\frac{12}{8} \\\\x=\frac{3}{2}$

then, take any one equation (either eq 1 or 2)

3x-3y=12​

3( $\frac{3}{2}$ ) - 3y =12

$\frac{9}{2} - 3y = 12\\\\\frac{9 - 6y}{2} = 12\\\\9 - 6y = 12 * 2\\9 - 6y =24\\(-6y) = 24-9\\(-6y) = 15\\y=\frac{15}{-6}$
