S/g=7/5, s=7g/5
s=g if s-30=g+30 using s found above...
7g/5 -30=g+30
(7g-150)/5=g+30
7g-150=5g+150
2g=300
g=150, and since s=7g/5, s=210
So Simon started with 210 pencils and Greg started with 150 pencils.

Hey, It looks like you're in Algebra and I'm here to give the best solution I can!
To write the equation, you are going to use the Standard Form. Standard Form is one way of solving this problem, and it is used to find the x,and y-intercepts of a problem.
Standard Form can be written using the equation <span>ax+by=c
</span>In your problem, you will write the equation like so, with 'x' representing T-Shirts, and 'y' representing pants:
<span>
8x+5y=220</span>
Now, in order to find the x-intercept you need to substitute a 0 for the 'y' variable and solve the new equation, 8x=220.
I'm sure you know you need to divide both sides by 8 which will give you the answer x=27.5.
Now, in order to find 'y' you would substitute a 0 for the 'x' variable which will give you an equation that should look like 5y=220.
Then, divided both sides by 5 to get your y-intercept.
y=44
Finally,you know that each T-Shirt (x) is $27.50, and each pair of pants(y)costs $44
-I hope this helped you, Sincerely, Auhrevo!
