Question

What is the value of x in the equation 2 (x + 3) = 4 (x minus 1)?

Answer 1

The value of x is $x=5$

Step-by-step explanation:

The equation we have is:

$2(x+3) = 4(x-1)$

We start by applying the distributive property to rewrite the terms in the brackets:

$2x + 2\cdot 3 = 4x - 4\cdot 1\\2x+6=4x-4$

Now we subtract $-2x$ on both sides:

$2x+6-2x = 4x-4-2x\\6 = 2x-4$

Now we add +4 on both sides:

$6+4 = 2x-4+4\\10 = 2x$

And now we divide by 2 on both sides:

$\frac{10}{2}=\frac{2x}{2}\\x=\frac{10}{2} = 5$
