Answer:
![a=(m+2f^2)/(d)\\\\ B=(3T)/(H)](https://img.qammunity.org/2021/formulas/mathematics/high-school/t7w97t6uyeu02vr1ttbc25zfupk8rbxxm0.png)
Explanation:
1.) Find a
Solve the given equation for a (change it to lool like a=...). Isolate the variable a to find its value. Subtract 2f² from both sides:
![m+2f^2=ad-2f^2+2f^2\\\\m+2f^2=ad](https://img.qammunity.org/2021/formulas/mathematics/high-school/28xe6dc17ozae3ige5yxv49157ep1h60yd.png)
Divide both sides by d:
![(m+2f^2)/(d)=(ad)/(d)\\\\ a=(m+2f^2)/(d)](https://img.qammunity.org/2021/formulas/mathematics/high-school/8zy52luuragjj39irece6mflm7p1xlyegc.png)
2.) Find B
Solve the equation for B (change it to look like B=...). Isolate the variable B to find its value. Simplify:
![(1)/(3)HB=T\\\\(HB)/(3)=T](https://img.qammunity.org/2021/formulas/mathematics/high-school/gdnixaepibpdleywm9aztza1pqhpsrpxm4.png)
Multiply both sides by 3:
![3((HB)/(3))=3(T)\\\\ HB=3T](https://img.qammunity.org/2021/formulas/mathematics/high-school/foh16qshs5ojrl26x1jaisa3b7jzv6nw5m.png)
Divide both sides by H:
![(HB)/(H)=(3T)/(H)\\\\ B=(3T)/(H)](https://img.qammunity.org/2021/formulas/mathematics/high-school/efiv7bk53n0j2eq0nxreeo1msjn6u9xehe.png)
