so
[-30 -5 ] [-20 - 4 ]
[+20 +30] + [-12 -32 ]
[-35 +35] [ 24 +32 ]

woah wait.. how in the world did you get that?

now we have to add these two matrices to get the answer

ok simply multiply the elements of matrix A with -5
and B with +4 we get the above rresult

ooh ook.. and now just add them to get the answer?:)

ok hold on...

-50 -9
8 -2
59 67

right?

but thats not an option.. these r the options i have:

[-50 -9]
[8 - 2 ]
[-11 +67]

simply your addition was wrong

ok i m waiting for the next one

i posted it :)

now multiply 2 with the matrix

take the result on the other side

ok.. i got
4 -16
-8 4
for the first part..

now what?

take this matrix on the other side

what does that mean? like i add it with the other one?

if u have the case like
X +Y =Z
what u do is to find X
X= Z-Y

oh so subtract the 1st one with the 2nd one?

ok i got
0 -22
-10 12
is that right?

no.. its not an option..:/

what did i do wrong?

could you please show me how?

[4 -6] - [4 -16]
[2 -8] [-8 4]

i got
0 -22
10 -12
but thats not an option either.

0 10
10 -12

thats still not an option?

u again made mistake in addition and subtraction

the one you posted wasnt an option either..

this wholle thing is 2X
now u have to divide it by two to get the answer

got it or not?

i guess so.. heres another one

the third one was the answer

r u sure? can you tell me how you figured it out?

yea i got that, thanks:) i need help on the next question that i posted:)

do u know how to multiply a matrices

yep

then here we go

In question matrix is given
[TD=6 FG=3 S=2 PAT=1] this is of order 1*4

[6 3 2 1] * [ 3 ]
[ 2 ]
[ 1 ]
[ 0 ]

now multiply them and get the answer for team A

i got 36..

and thats an option!! thanks so much!!:)

no no no its 26

[18+ 6+2 +0] = 26

ooh.. well that's still an option.. thanks!!:)

now did u get the method to solve it ?

i never tried so hard to make someone learn something .
Now i can go sleep with ease..
