Answer 1

Answer:

Converting to standard form

In some cases (for example when solving systems of equations), we might want to bring an equation written in another form to standard form.

Let's bring the equation y=\dfrac{3}{8}x+5y=  

8

3

​  

x+5y, equals, start fraction, 3, divided by, 8, end fraction, x, plus, 5 to standard form:

\begin{aligned} y&=\dfrac{3}{8}x+5 \\\\ -\dfrac{3}{8}x+y&=5\quad\gray{\text{Put all variables on one side}} \\\\ -3x+8y&=40\quad\gray{\text{Multiply by denominator}} \end{aligned}  

y

​  

x+y

−3x+8y
