it was wrong

what is wrong about it?

jiteshmeghwal9 · Answer

first find the value of 'x' from one of the equation
$x+2y=9$
$x=9-2y$
now substitute he value in next equation & solve for 'y' :)

jiteshmeghwal9 · Answer

after getting the value of 'y' put the value in the equation
$x=9-2y$

to gt the value of x :)

anonymous · Answer

you have to solve x in the second equations

jiteshmeghwal9 · Answer

(9-2y)-y=6

jiteshmeghwal9 · Answer

solve this equation for y :)

anonymous · Answer

no your soving for x and the second equation

jiteshmeghwal9 · Answer

plz i m helping u. do it as i say :)

jiteshmeghwal9 · Answer

solve for y:-
(9-2y)-y=6
9-2y-y=6
9-3y=6
-3y=6-9
-3y=-3
y=1

jiteshmeghwal9 · Answer

substituting the value of y in the equation

x=9-2y
x=9-2(1)=7

jiteshmeghwal9 · Answer

so, x=7 & y=1 :)
