Question 80213
{{{5x-13=27}}}
First add 13 to both sides of the equation to get the x term alone:
{{{5x=40}}}
Divide each side of the equation by 5 to solve for x:
{{{highlight(x=8)}}}
----------------------------------------
{{{3w/8+7=65}}}
Subtract 7 from each side...
{{{3w=58}}}
Divide each side by 3 to solve for w:
{{{w=58/3}}}
Generally, they want the student to convert this improper fraction to a mixed number for the final answer:
{{{highlight(w=19+1/3)}}}
----------------------------------------
{{{d/4+18=24}}}
Subtract 18 from both sides...
{{{d/4=6}}}
Multiply each side by 4 to get d alone (the 4's cancel on the left side):
{{{highlight(d=24)}}}
