Answer 3

To solve the equation 72x + 68x = 420, you can combine the like terms on the left side of the equation:

72x + 68x = 140x

So the equation becomes:

140x = 420

To solve for x, divide both sides by 140:

140x/140 = 420/140

Simplify:

x = 3

Therefore, the solution to the equation 72x + 68x = 420 is x = 3.
