Question

Solve h=-b/2a for b this is a algebra question

Answer 1

`\sf Solve \ for \ b. \\ \\ h = (-b)/(2) a \\ \\ Flip \ equation \\ \\ (-1)/(2) ab = h \\ \\ Divide\ both \ sides\ by ((-a))/(2) \\ \\ (1)/(2)ab/ (-a)/(2) = h / -a / 2 \\ \\ b = (-2h)/(a)`

Answer 2

`h=-(b)/(2a)\\\\(b)/(2a)=-h\ \ \ \ |multiply\ both\ sides\ by\ 2a\\eq0\\\\\huge\boxed{b=-2ah}`
