Can someone tell me the steps for this: Whats the equation for x? 7x+3= 11x+3

Power:

Get the x's to one side and the non-x's to the other

Power:

Subtract 7x on both sides

Wandurlust:

I subtracted 3 from both sides and I was left with 7x=11x

Power:

Sure okay, then subtract 7x

Wandurlust:

Subtract 7x from what? the 11 or the 7?

Power:

Both sides

Wandurlust:

Ok but the answer is 4 so im confused

Power:

\(0=4x\) Divide by 4 on both sides 0 is your solution

Wandurlust:

Oh thanks

Wandurlust:

Wait im sorry im just confused why would I divide 4

Power:

To isolate x

Power:

Opposite of 4 times x is divide by 4

Wandurlust:

Oh ok thanks again
