Question

Consider the following equation, bh+hr=25 when solving for r

Answer 1

Answer:

$r=\frac{25-bh}{h}$

Step-by-step explanation:

Given : Consider the following equation, $bh+hr=25$

To find : Solving for r ?

Solution :

The equation is $bh+hr=25$ solve for r,

Subtract 'bh' both side,

$bh+hr-bh=25-bh$

$hr=25-bh$

Divide both side by 'h',

$\frac{hr}{h}=\frac{25-bh}{h}$

$r=\frac{25-bh}{h}$

Therefore, $r=\frac{25-bh}{h}$

Answer 2

Solve for r.

You want to get r by itself on one side on the equal sign.

bh + hr = 25

Subtract bh from both sides.

hr = 25 - bh

Divide h on both sides.

r = 25 - bh / h

The two h's cancel each other out.

r = 25 - b

Hope this helps!
