Question

Change the equation to show what it would look like if you were getting the value of (b):

Show steps please.


`A= (1)/(2)h(b+c)`

Answer 1

`A= (1)/(2)h(b+c) \\ 2A=h(b+c)\\ 2A=hb+hc\\ hb=2A-hc\\ b=(2A-hc)/(h)`

Answer 2

`A=(1)/(2)h(b+c)\ \ \ \ \ |multiply\ by\ 2\\\\ 2a=h(b+c)\ \ \ \ |divide\ by\ h\\\\ (2a)/(h)=b+c\ \ \ \ \ |subtract\ c\\\\ (2a)/(h)-c=b\\\\Solution\ is\ b=(2a)/(h)-c`
