1. Equation #1: <span>g+s=150
Equation #2: </span><span>8g +5s = 900
2. Solution to the system:
</span>G = 150 – s
<span>8(150-s)+5s=900 </span>
<span>1200-8s+5s=900 </span>
<span>-900 -900 </span>
<span>300/3-3s/3
</span>
3. Idk about this one...

last term 
and no of terms 
And sum of n terms is given by
![S_n=\frac{n}{2}[a_1+a_n]](https://tex.z-dn.net/?f=S_n%3D%5Cfrac%7Bn%7D%7B2%7D%5Ba_1%2Ba_n%5D)
![S_n=\frac{13}{2}[16+98]](https://tex.z-dn.net/?f=S_n%3D%5Cfrac%7B13%7D%7B2%7D%5B16%2B98%5D)
Sp sum of n terms is 741
Answer:
in -5y+8x=-18 and 5y+2x=58
x = 4
