Steps for finding the solution

We have 12x + 456 = 345678

First, we move the non x terms to the RHS of the equation. To do this, we subtract 456 from both sides.

Note: if a = b, then a - c = b - c

Therefore, 12x + 456 - 456 = 345678 - 456

or, 12x = 345222

Next, divide both sides by 12, which is the coefficent of x

Note: if a = b, then a ÷ c = b ÷ c

12x/12 = 345222/12

x = 345222/12

To simplify, divide both numerator and denominator by 6, which is the GCF of 345222 and 12:

x = 57537/2 or, x = 28768.5
