Question

1. solve for b. a = x + by
2. solve for a. c = a - b
3. solve for h. x = \frac{ah}{y}

Explanation:

Step1: Isolate the term with b

Subtract x from both sides of $a = x+by$:
$a - x=by$

Step2: Solve for b

Divide both sides by y (assuming $y
eq0$):
$b=\frac{a - x}{y}$

Step3: Solve for a in $c = a - b$

Add b to both sides:
$a=c + b$

Step4: Solve for h in $x=\frac{ah}{y}$

Multiply both sides by y:
$xy = ah$

Step5: Solve for h

Divide both sides by a (assuming $a
eq0$):
$h=\frac{xy}{a}$

Answer:

1. $b=\frac{a - x}{y}$
2. $a=c + b$
3. $h=\frac{xy}{a}$
