Question

4x + 12 = 36\
\\(\frac{x}{4}\\) + 6 = 12

Explanation:

Step1: Isolate term with $x$ (1st equation)

$4x + 12 - 12 = 36 - 12$
$4x = 24$

Step2: Solve for $x$ (1st equation)

$x = \frac{24}{4}$

Step3: Isolate term with $x$ (2nd equation)

$\frac{x}{4} + 6 - 6 = 12 - 6$
$\frac{x}{4} = 6$

Step4: Solve for $x$ (2nd equation)

$x = 6 \times 4$

Answer:

For $4x + 12 = 36$, $x = 6$
For $\frac{x}{4} + 6 = 12$, $x = 24$
