Question

solve for x using cross - multiplication.
$\frac{3x + 2}{4}=\frac{x + 4}{2}$
$x =?$

Explanation:

Step1: Cross - multiply

$(3x + 2)\times2=(x + 4)\times4$
$6x+4 = 4x+16$

Step2: Move terms with x to one side

$6x-4x=16 - 4$
$2x=12$

Step3: Solve for x

$x=\frac{12}{2}$

Answer:

$x = 6$
