Question

h

Answer 1

hi,
let's number the 2 equations 1st
3x + 3y = 10 -----(1)
-9x -9y = -30 ----(2)

now divide the (2) by 3 ..wt will u get ?

Answer 2

\[-\frac{ 9x }{ 3 } -\frac{ 9y }{ 3 } = -\frac{ 30 }{ 3 }\]
did u get it?

Answer 3

Hey!! Don't u get it !! ?
There' s something wrong with this question....
-3x -3y = -10
0 = -10 + 3x +3y
3x + 3y = 10
it's the same expression ... as (1)
to solve a system of equation with 2 unknown variables there should be at least 2 different equations. What u've got here r 2 equation which r equal to each other...

U can't solve this with wt u've got here. Pls check whether the 2 equations r right....

Hope this will hep u !
