Verified answer

isolate the x, so add 3 to both sides

x=11

In solving any equation, the goal is to get the variable (x) on one of the "equals" sign and all of the constants (8, -3) on the other side.

x - 3 = 8

Since the 3 is being subtracted, we add a 3 to both sides...

x - 3 + 3 = 8 + 3

The "- 3 + 3" cancel out, leaving...

x = 8 + 3

Combine like terms...

x = 11

And there's your answer!

x – 3 = 8

x – 3 + 3 = 8 + 3

x = 8 + 3 = 11

----

Carry -3 to the other side

x = 8 + 3

x = 11

You are right

Our aim is to find the value of "x"

so we have to make the equation in the form "x = any value".

x - 3 = 8

[whenever we transpose one number from L.H.S to R.H.S or the opposite, + will become - and - will become + ]

by transposing -3 to R.H.S(Right Hand Side) ,it will become +3,

we will get

x = 8+3

therefore

x = 11

AN Alternative Method....:---

x - 3 = 8

add 3 to both sides, we will get

x - 3 + 3 = 8 + 3

rearrange +3 and -3

x + 3 - 3 = 11

x = 11

To solve an equation for the variable x, you must undo the problem(isolate the x) by doing the opposite of what is already done.

So, since x-3=8, you must add 3 to both sides because you must do whatever you do to one side to the other in order to balance the equation.

Chronologically, we would get x=11 as our answer.

If this was a multi-step equation, you would have had to follow the order of operations backwards.

So, PEMDAS would become SADMEP.

You would always have to add or subtract first before you multiply or divide, but the normal rule still applies for parenthesis and exponent.

You have to do them first.

x − 3 = 8.....add 3 to both sides

x = 11

I strongly suggest you talk to your teacher. Someone has not adequately explained equations to you.

Because the equals sign " = " tells you the terms on either side of it have the same value. Any operation that is performed on both sides yields another equation that must be true.

Something take away 3 is eight. If you took away 3 from minus 11 you would have -14.
