Doesn't really matter tuesday monday... what's the difference? Nothing much can happen except for the fact that i may lose 2 freaking papers
and how do you know? which school?

i am in jeddah but the days are same worldwide

 

[Addoozz]

this is w11 qp 21 # 11(b)
how do we solve this (without a calculator)
actually i have no idea how to do it at ALL

first find determinant and divide using one. then swap 2 with 3 and make 1 and 4 negative.multiply and get the answer.

 

[aliiiiiiiiii]

Hey! I live in khobar, too! Yeah, Math P42 and Physics P11 next tuesday

how u have it tuseday its on 14next wed

sure IF you're ready to pay
Yeah... this tue is P2 (piece of cake) and then monday is P4 (whole cake)

 

[GlitteringLights]

you just inverse it by finding the determinant of the matrix which is (2x3-1x4) and then we write the answer as 1/the determinant
we then multiply the 1/determinant with the matrix but we must switch 2 and 3 location and add negative to 1 and 4 so it becomes
1/2 times The New matrix which is = (3 -1)
(-4 2)

thank you, though i already got the answer

Why thank you... that's even better

Math is LOVE <3 although i do know some subjects that could be worth some puking

are you taking core mathmatics?
1/2(2/3+1/4)
for the bracket part take LCM
1/2(8+3/12)
1/2(11/12)
open brackets
11/24 is the final answer
