Steps for finding the solution

We have 3x = 42

Divide both sides by 3, which is the coefficent of x

Note: if a = b, then a ÷ c = b ÷ c

3x

3

=

42

3

x =

42

3

To simplify, divide both numerator and denominator by 3, which is the GCF of 42 and 3:

x =

14

1

or, x = 14

Answer 2

Answer:

Hence, the value of the equation is 14.

Step-by-step explanation:

As per the data given in the question,

We have to find the value of the equation,

The given equation,

$3x= 42$

Here we will use the transposition method.

Now, divide both sides by $3$ we get

=> $\frac{3x}{3}=\frac{42}{3}$

Simplifying it further,

=> $x = 14$

So, the required solution is 14.
