![b_1=\frac{2A}{h}-b_2](https://tex.z-dn.net/?f=b_1%3D%5Cfrac%7B2A%7D%7Bh%7D-b_2)
Step-by-step explanation:
Given expression is;
![A=\frac{h(b_1+b_2)}{2}](https://tex.z-dn.net/?f=A%3D%5Cfrac%7Bh%28b_1%2Bb_2%29%7D%7B2%7D)
Solving for ![b_1](https://tex.z-dn.net/?f=b_1)
Multiplying both sides by 2
![2*A=\frac{h(b_1+b_2)}{2}*2\\2A=h(b_1+b_2)](https://tex.z-dn.net/?f=2%2AA%3D%5Cfrac%7Bh%28b_1%2Bb_2%29%7D%7B2%7D%2A2%5C%5C2A%3Dh%28b_1%2Bb_2%29)
Dividing both sides by h
![\frac{2A}{h}=\frac{h(b_1+b_2)}{h}\\\frac{2A}{h}=b_1+b_2](https://tex.z-dn.net/?f=%5Cfrac%7B2A%7D%7Bh%7D%3D%5Cfrac%7Bh%28b_1%2Bb_2%29%7D%7Bh%7D%5C%5C%5Cfrac%7B2A%7D%7Bh%7D%3Db_1%2Bb_2)
Subtracting
from both sides
![\frac{2A}{h}-b_2=b_1+b_2-b_2\\\frac{2A}{h}-b_2=b_1\\b_1=\frac{2A}{h}-b_2](https://tex.z-dn.net/?f=%5Cfrac%7B2A%7D%7Bh%7D-b_2%3Db_1%2Bb_2-b_2%5C%5C%5Cfrac%7B2A%7D%7Bh%7D-b_2%3Db_1%5C%5Cb_1%3D%5Cfrac%7B2A%7D%7Bh%7D-b_2)
![b_1=\frac{2A}{h}-b_2](https://tex.z-dn.net/?f=b_1%3D%5Cfrac%7B2A%7D%7Bh%7D-b_2)
