You can put this solution on YOUR website!
your first equation is:
\n" ); document.write( "3x-1 = 5x-y
\n" ); document.write( "you need to solve for y in order to graph this equation.
\n" ); document.write( "if you add y to both sides of this equation, then the y moves from the right side to the left side.
\n" ); document.write( "if you subtract (3x-1) from the left side of the equation, then (3x-1) moves to the right side.
\n" ); document.write( "you get:
\n" ); document.write( "y = 5x - (3x-1) which becomes:
\n" ); document.write( "y = 5x - 3x + 1 which becomes:
\n" ); document.write( "y = 2x + 1
\n" ); document.write( "now you can graph the equation by plotting x and y points.
\n" ); document.write( "the graph will look like this:
\n" ); document.write( "\"graph+%28600%2C300%2C-5%2C5%2C-5%2C5%2C2x%2B1%29\"
\n" ); document.write( "-----
\n" ); document.write( "your second problem looks like you mean absolute value of which would make the x between 2 vertical lines.
\n" ); document.write( "the equation would look like this:
\n" ); document.write( "y = |x| + 3
\n" ); document.write( "-----
\n" ); document.write( "those vertical lines are found on your keyboard usually on the right side right above the enter key on the same key with the \ but you hold the shift key down and then hit the key, otherwise known as SHIFT \ which gets you |.
\n" ); document.write( "-----
\n" ); document.write( "you do not have to convert this equation, but you need to plot x and y values and then graph.
\n" ); document.write( "the graph will look like this:
\n" ); document.write( "\"graph%28600%2C300%2C-5%2C5%2C-1%2C5%2Cabs%28x%29%29\"
\n" ); document.write( "-----
\n" ); document.write( "the other way to write |x| is to call it abs(x) which is consistent with algebra.com terminology that most tutors know.
\n" ); document.write( "-----
\n" ); document.write( "some other tidbits in case you don't know.
\n" ); document.write( "algebra.com terminogy.
\n" ); document.write( "x^2 is the same as x squared.
\n" ); document.write( "x^n is the same as x to the nth power
\n" ); document.write( "sqrt(x) is the same as the square root of x
\n" ); document.write( "root(n,x) is the same as the nth root of x
\n" ); document.write( "-----
\n" ); document.write( "* means multiply
\n" ); document.write( "/ means divide
\n" ); document.write( "use parentheses to show order of computations.
\n" ); document.write( "5+3*2 is the same as 5 + (3*2) = 5 + 6 = 11
\n" ); document.write( "(5+3)*2 is the same as 8*2 = 16
\n" ); document.write( "operations within parentheses are done first, working from the inner set of parentheses to the outer set of parentheses.
