How do you solve 4x - 2?

Answer 1

This is an expression and not an equation (because there is no equals sign), so it can not be solved, only factored.

4X - 2

2(2X - 1)

=======

Assuming that you meant 4x - 2 = 0 Now that it's been factorized, you can see that there are 2 factors; 2 and 2(2x-1)

You have a definite value of 2, but you need to equate what's inside the brackets to 0.

so, 2x -1 = 0

What number multiplied by 2, and taken 1 from, results in zero?

The answer is 1/2 (a half, 0.5)

Why? -Well, 2 times 1/2 is 1.

And it logically follows that 1-1 = 0

We can now say that there are 2 values for x.

We write it like this as a final answer:

x=2, x=1/2
