Solve the linear equations.

OpenStudy (anonymous):

\[\left(\begin{matrix}4x-3 \\ 2\end{matrix}\right)+ \left(\begin{matrix}3 \\ 8\end{matrix}\right)= \left(\begin{matrix}7x+3 \\ 4\end{matrix}\right)\]

OpenStudy (anonymous):

is that matrix?

OpenStudy (anonymous):

What do you mean?

OpenStudy (anonymous):

what is the meaning of equation that you write

OpenStudy (anonymous):

Like what kind of equation is it? Sorry i am no good at math :/

OpenStudy (turingtest):

I also am confused, what math is this supposed to be?

OpenStudy (anonymous):

Those are supposed to be fractions.

OpenStudy (turingtest):

ah...

OpenStudy (anonymous):

But i am not sure how to write fractions.

OpenStudy (turingtest):

\[\frac{4x-3}2+\frac38=\frac{7x+3}4\]multiply everything by 8 to get rid of the denominator

OpenStudy (anonymous):

)))) brilliant

OpenStudy (anonymous):

Sorry :/ yes that is how it is supposed to look.

OpenStudy (anonymous):

I am not sure how to multiply like 8*7x+3/4 like that?

OpenStudy (turingtest):

yes \[8\cdot\frac{4x-3}2+8\cdot\frac38=8\cdot\frac{7x+3}4\]now you can cancel out the common factors 8/2=4 8/8=1 8/4=2 so this becomes\[4(4x-3)+3=2(7x+3)\]now distribute, collect like terms, and isolate x

OpenStudy (anonymous):

so then it = 16x-12+3=14x+6 correct?
