Question

in the system of x+2y=9 and x-y=6. what would be substituted for x and the second equation

Answer 1

rear-rage your first equation
x = 9-2y right?

Answer 2

*rearrange

Answer 3

it was wrong

Answer 4

what is wrong about it?

Answer 5

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' :)

Answer 6

after getting the value of 'y' put the value in the equation
\(x=9-2y\)

to gt the value of x :)

Answer 7

you have to solve x in the second equations

Answer 8

(9-2y)-y=6

Answer 9

solve this equation for y :)

Answer 10

no your soving for x and the second equation

Answer 11

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

Answer 12

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

Answer 13

substituting the value of y in the equation

x=9-2y
x=9-2(1)=7

Answer 14

so, x=7 & y=1 :)
