What is the number that ‘x’ stands for?


We want something like
Solving Algebra Mathematics equations the easy way
With ‘x’ on the left and a number on the right.

Let’s start by making the 9 disappear. To do this we must subtract
9 from
BOTH sides of the equation.
Algebra made easy
On the left side: 9 – 9 equals zero

On the right side: 4 – 9 equals -5


We now have
Solving Algebra mathematics problems
Next step: 5/2 must go!

Well, 5/2 is multiplied by ‘x’ so we must divide by the same number
5/2. Or we can multiply by the opposite fraction 2/5. It’s easier.

Let’s do it on
BOTH sides.
Solving Algebra equations the easy way
On the left side: 2/5 times 5/2 is equal to 1. Because the ‘1x’ is the same as
only ‘x’ we got the ‘x’ alone on the left side.

On the right side: -5 times 2/5 is equal to -2


So the final answer is
Algebra online for absolute beginners
Which is true if we try to use -2 instead of ‘x’ in the starting equation.
Congratulations!

The equation is solved !
In rapid motion...
