Question

If 4x- 7 = 2x, then 2x = ?

Answer 1

If $4x-7=2x$, then $2x=7$.

Hope this helps.

Answer 2

Answer:

7

Step-by-step explanation:

We solve for x first.

So: 4x - 7 = 2x

Subtract 2x from both sides: 4x - 2x - 7 = 2x - 2x

2x - 7 = 0

Add 7 to both sides: 2x - 7 + 7 = 0 + 7

2x = 7

Divide by 2: $\frac{2x}{2}$ = $\frac{7}{2}$

x =  $\frac{7}{2}$

Now, we substitute x for  $\frac{7}{2}$ like this:

2 ( $\frac{7}{2}$) = 7
