Question

Solve the linear equations.

Answer 1

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

Answer 2

is that matrix?

Answer 3

What do you mean?

Answer 4

what is the meaning of equation that you write

Answer 5

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

Answer 6

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

Answer 7

Those are supposed to be fractions.

Answer 8

ah...

Answer 9

But i am not sure how to write fractions.

Answer 10

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

Answer 11

)))) brilliant

Answer 12

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

Answer 13

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

Answer 14

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

Answer 15

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