Hey there!☺


Answer:\boxed{x=2}


Explanation:


5x-1=7+x

Let's start with simplifying both sides:


5x+-1=7+x\\5x-1=x+7

Now we have to subtract x from both sides:


5x-1-x=x+7-x\\4x-1=7

Now add 1 to both sides:


4x-1+1=7+1\\4x=8

In our fourth step, we have to divide both sides by 4:


(4x)/(4)=(8)/(4)

Now we need to simplify 8/4:


(8)/(4)=2

Now we got our answer!


x=2

Hope this helps!☺

Answer:

x=2

Explanation:

5x – 1 = 7 + x

Subtract x from each side

5x-x – 1 = 7 + x-x

4x-1 = 7

Add 1 to each side

4x-1+1 = 7+1

4x = 8

Divide each side by 4

4x/4 = 8/4

x =2
