What is the solution to the system of equations y=x+3, y=3x+1
Snezhnost [94]

Substitution method

y = x + 3   (*)

y = 3x + 1  (**)

Substitute (*) to (**):

3x + 1 = x + 3      <em>subtract 1 from both sides</em>

3x = x + 2       <em>subtract x from both sides</em>

2x = 2        <em>divide both sides by 2</em>

<h3>x = 1</h3>

Put the value of x to (*):

y = 1 + 3

<h3>y = 4</h3><h3>Answer: x = 1 and y = 4 → (1, 4).</h3>

What is 0.482 repeating as a simplified fraction?
weeeeeb [17]

the idea being, we multiply the value by some power of 10 just to move the repeating digits to the left of the decimal point.  We have 3 digits, we'll use 1000, anyhow, without further adieu,


\bf \begin{array}{|ccl|ll}&#10;\cline{1-3}&#10;\stackrel{\qquad}{x=0.\overline{482}}&&\\&#10;\cline{1-3}&#10;&&\\&#10;\stackrel{\textit{3 digits, we use 3 zeros}}{1000\cdot x}&=&482.\overline{482}\\&#10;&&482+0.\overline{482}\\&#10;&&482+x\\&#10;&&\\&#10;\cline{1-3}&#10;\end{array}\implies 1000x=482+x&#10;\\\\\\&#10;999x=482\implies x=\cfrac{482}{999}
