Question

A=h(a+b)/2 solve for a

Answer 1

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

Answer 2

Answer:

((2A)/h)- b=a

Step-by-step explanation:

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.
