Question

Solve for c: A=1/2(b+c)h

/ fraction bar

Answer 1

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

Answer 2

`A=(1)/(2)(b+c)h\ \ \ \ |Divide\ by\ h\\\\ (A)/(h)=(1)/(2)(b+c)\ \ \ \ |Multiply\ by\ 2\\\\ (2A)/(h)=b+c\ \ \ \ |Subtract\ b\\\\ (2A)/(h)-b=c\\\\Solution\ is\ c=(2A)/(h)-b.`
