Question

solve the following equation and check the result is x/3plusx/4=42​

Answer 1

Answer:

$</p><p>\begin{gathered} \frac{x}{3} + \frac{x}{4} = 42 \\ \\ x( \frac{7}{12} ) = 42 \\ \\ x = 12 \times 6 = 72\end{gathered}3x+4x=42x(127)=42x=12×6=72</p><p>$

This is the answer to understand.

Hope it helps.

Please follow and thanks.

Answer 2

$\frac{x}{3} + \frac{x}{4} = 42$

$\frac{4x + 3x}{12} = 42$

$7x = 42 \times 12$

$7x = 504$

$x = \frac{504}{7}$

$x = 72$
