Question 241740
If one number is six more than the other number and their sum is 30,we can say:
{{{x+(x+6)=30}}}
Now solve for x to find the value of one number.
{{{2x+6=30}}}
{{{2x=30-6}}}
{{{2x=24}}}
{{{x=24/2}}}
{{{x=12}}} ...this is one number
.
The other number is:
{{{x+6=12+6=18}}}
.
==========================================
.
Let pants = x
Let coats = 3x
Their sum = 180
So we can say their equation is:
{{{x+3x=180}}}
{{{4x=180}}}
{{{x=180/4}}}
{{{x=45}}}
.
Done!  :)
