Question 158918
{{{5x+10=-20}}}
First we solve for x:
{{{5x=-20-10}}}
{{{5x=-30}}}
{{{cross(5)x/cross(5)=cross(-30)6/cross(5)}}}
{{{x=-6}}}
{{{graph(100,100,-10,10,-10,10,x=-6)}}} ----> changing the variable does not make any difference on how you solve it.The variable is just a reference, you can make any reference or letters you want to represent it.
Thank you,
