Question

make x the subject h=a/2(b-x/d)

Answer 1

Answer:

x = d ( b - 2h/a)

Step-by-step explanation:

The basic ideas when rearranging equations, is that both sides of the equation are equal to each other. So as long as you do the same thing to both sides they will continue to be equal to each other.

h= a/2 (b-x/d)

divide both sides by a/2 (same as multiply by 2/a)

2h/a = b - x/d

subtract b from both sides

2h/a - b = - x/d

multiply both sides by -1

b - 2h/a = x/d

multiply both sides by d

d (b - 2h/a) = x

ta-da. If you want you can flip the sides around to make it look neater

x = d (b - 2h/a)
