Question

Solve 19 - 4x = 2x + 1

Answer 1

Answer: The answer is 3

Step-by-step explanation: I’m smart.

Answer 2

x= 3.

Explanation:

1. Write the expression.

`19 - 4x = 2x + 1`

2. Subtract 19 from both sides of the equation.

`19 - 4x-19 = 2x + 1-19\\ \\-4x=2x-18`

3. Subtract 2 from both sides of the equation.

`-4x-2x=2x-18-2x\\ \\-6x=-18`

4. Divide both sides by "-6".

`(-6x)/(-6) =(-18)/(-6) \\ \\x=3`

5. Verify the answer by substituting the calculated value of m into the original equation and simplifying.

`19 - 4(3) = 2(3) + 1\\ \\19-12=6+1\\ \\7=7`

That's correct. Therefore, x= 3 is the correct answer!
