Question

cated variable.

1. ( u = 2x - 2 ), for ( x )

( x = \frac{u + 2}{2} )

1. ( g = ca ), for ( a )

Explanation:

Step1: Isolate term with $x$

Add 2 to both sides:
$u + 2 = 2x$

Step2: Solve for $x$

Divide both sides by 2:
$x = \frac{u + 2}{2}$

Step3: Isolate term with $a$

Start with $g = ca$

Step4: Solve for $a$

Divide both sides by $c$ ($c
eq 0$):
$a = \frac{g}{c}$

Answer:

$x = \frac{u + 2}{2}$
$a = \frac{g}{c}$
