How to determine solutions to a system of linear equations

Cerrena [4.2K]

$\bf \begin{cases}
\boxed{y}=-\frac{1}{3}x+2\\\\
x=2y+6
\end{cases}
\\\\\\
\textit{using substitution on the \underline{2nd equation}}
\\\\\\
x=2\left( \boxed{-\frac{1}{3}x+2} \right)+6\implies x=-\cfrac{2x}{3}+4+6\implies x=-\cfrac{2x}{3}+10
\\\\\\
x=\cfrac{-2x+30}{3}\implies 3x=-2x+30\implies 5x=30
\\\\\\
x=\cfrac{30}{5}\implies \boxed{x=6}$

and since we know now what "x", let's use that in either equation, say the first equation,

$\bf y=-\cfrac{1}{3}x+2\implies y=-\cfrac{1}{3}(6)+2\implies y=-2+2\implies y=0$

another way to do it is by "elimination", depending on the equations, one way may work quicker than the other, in this case, substitution was the simpler one, because the first equation is already solved for "y", so we just grabbed it and plugged it in the 2nd equation.

Explain how to use a pattern to find 35.6 divided by 10 to the power of 2

posledela

As we know, sometimes questions such as these that include the powers and patterns can be a little confusing. I'll walk you through the process of finding this answer.

Firstly, we both know that 10 to the power of 2 simply means this :

10 * 10 = 100

Now, considering we already know what 10 to the power of 2 is, it makes the rest of the question a lot easier. All we have to do is divide 35.6 by the numbers we got.

35.6 / (10 * 10) = 0.356

There you have it, the answer is 0.356. If you need further assistance or you don't understand something, don't hesitate to ask me! I'm always open to people commenting on my profile or even sending me a private message. :)
