    i'm having trouble graphing linear equations.. especially with fractions.. such as how do you graph y=1/2x+3 ? But, if you want to just look at the equation and graph it, first draw the y intercept(just a point). that way you already have one point. Then look at the slope and use rise/run and use that point...

    Add the x terms and the constants on the left side of the equation. Subtract 5x from both sides of the equation: Add 69 to both sides of the equation: Divide both sides by 49: The answer is x=3. Check the solution by substituting 3 in the original equation for x. If the left side of the equation equals the right side of the equation after the substitution, you have found the correct answer.
