Answer:
2A/h - b =a
Step-by-step explanation:
A=h(a+b)/2
Multiply each side by 2
2A =h(a+b)/2*2
2A=h(a+b)
Divide each side by n
2A/h = h(a+b)/h
2A/h = a+b
Subtract b from each side
2A/h - b =a+b-b
((2A)/h)- b=a
First get the 2 to the left by multiplying each side by 2. Then, get h to the right by dividing each side by h. Lastly, subtract b from each side.
