How do you do equations?

Answer 1

It's a complicated question.

I'll give you an example:

2X+5=25

then you do order of operations

subtract 5 from both constants

which then gives you:

2X=20

then since you cant combine a constant and a variable together you have to divide by the variable. which then gives you:

X=10

and for the future, X is 1X. and X is the answer you could give for an answer

This is a pretty big topic, but you can make a good start by remembering:

Your goal is to get the variable by itself on one side (usually the left side).

To do this, follow the "Golden Rule": What you do to one side, you must do to the other.

Among the things you can do to both sides at once are -

Add a number

Subtract a number

Multiply by a number

Divide by a number

Take the reciprocal of the whole side

Square the whole side

Take the logarithm of the whole side

Make the whole side an exponent of 10 or some other base
