Maybe theirs no solution.

@Vocaloid

This would be without the equal sign right

Answer 14

Answer 16

@Nnesha

Answer 17

so should I just try -4

Answer 18

Answer 19

a,b,c,d are the coefficients

Answer 20

okay I used the numbers

Answer 21

would it be 2 and 6

Answer 22

i'm not sure how u got 2 and 6?
what's -2x+6y?

Answer 23

you have to find the value of `a-b+c+d`

Answer 24

\[\left[\begin{matrix}\color{red}{a} &\color{green}{ c} \\ \color{blue}{b}& \color{orange}{d}\end{matrix}\right]\left(\begin{matrix}x \\ y\end{matrix}\right)=\left(\begin{matrix}C_1\\ C_2\end{matrix}\right)\]
a,b,c,d values \[\large\rm \color{ReD}{a}x+\color{blue}{b}y=C_1 \]\[\large\rm \color{green}{c}x+\color{orange}{d}y=C_2 \]
\[\large\rm find~~~\color{red}{a}-\color{blue}{b}+\color{green}{c}+\color{orange}{d}\]

Answer 25

Well there is nothing more you can do with -2x+6y

Answer 26

what's -2x+6y ? how did you get that?

Answer 27

I did a-d which is 2-2

Answer 28

Answer 34

yes correct

Answer 35

that's -2

Answer 36

then I added the c value which is 8

Answer 37

that is 6

Answer 38

then didi 6-(-2)

Answer 39

8?

Answer 40

8-2 =6 correct
and then we have to `add ` d

Answer 41

d is -2?

Answer 42

a-b+c `+d`
yes d is -2
