Question

Make x the subject of h = 4(x + 3y) + 2

Plz help

Answer 1

`x=(h)/(4)-3y-(1)/(2)`

Explanation:

This equation has "h" as the subject. Now, making "x" the subject means to use algebra and re-arrange the equation so we have "x = SOMETHING".

First, we will use distributive property on the RHS of the equation. The distributive property is:

`a(b+c)=ab+ac`

So, we have:

`h=4(x+3y)+2\\h=4x+12y+2`

Since we want "x" as the subject, we put "x" term on one side and everything else on another and solve for x. Shown below:

`h=4x+12y+2\\4x=h-12y-2\\x=(h-12y-2)/(4)\\x=(h)/(4)-3y-(1)/(2)`

This is the answer.
