If [tex]4x-7=2x[/tex], then [tex]2x=7[/tex].

Hope this helps.

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: [tex]\frac{2x}{2}[/tex] = [tex]\frac{7}{2}[/tex]

x =  [tex]\frac{7}{2}[/tex]

Now, we substitute x for  [tex]\frac{7}{2}[/tex] like this:

2 ( [tex]\frac{7}{2}[/tex]) = 7
