Given expression:
A = [tex]\frac{1}{2}(b_{1} + b_{2} )[/tex]
Solve for b₁;
Solution:
This is a subject of the formula problem.
Given expression:
A = [tex]\frac{1}{2}(b_{1} + b_{2} )[/tex]
First, multiply both sides by 2;
2 x A = 2 x [tex]\frac{1}{2}(b_{1} + b_{2} )[/tex]
2A = b₁ + b₂
Then subtract b₂ from both sides;
2A - b₂ = b₁ + b₂ - b₂
b₁ = 2A - b₂
The solution is b₁ = 2A - b₂
