Final answer:

By combining like terms and simplifying the equation 0.4(x−4) + 0.6x = 1.4, we find that x equals 3.

Step-by-step explanation:

To solve for x in the provided equation, 0.4(x−4)+0.6x=1.4, we'll combine like terms and simplify. First, distribute the 0.4 into the parentheses:

0.4x - 0.4(4) + 0.6x = 1.4

0.4x - 1.6 + 0.6x = 1.4

Combine the x terms:

(0.4x + 0.6x) - 1.6 = 1.4

1.0x - 1.6 = 1.4

Now, isolate x by adding 1.6 to both sides of the equation:

1.0x = 1.4 + 1.6

1.0x = 3.0

Finally, divide by 1.0 to solve for x:

x = 3.0

Therefore, the solution to the equation is x = 3.
