Question

Ma=a-c÷a solve for a

Answer 1

`a=\pm \sqrt{(c)/(1-m)}`

Explanation:

Given the equation

`ma=a-c/ a`

Rewrite it using fraction:

`ma=a-(c)/(a)`

Multiply it by a:

`ma\cdot a=a\cdot a=(c)/(a)\cdot a\\ \\ma^2=a^2-c\\ \\ma^2-a^2=-c\\ \\a^2(m-1)=-c\\ \\a^2=(-c)/(m-1)\\ \\a^2=(c)/(1-m)\\ \\a=\pm \sqrt{(c)/(1-m)}`
