Question

What will you get if you do this

4x-3x+9=20

Answer 1

This can be solved like this:

4x-3x+9=20

Solving 4x-3x

x+9=20

Transposing +9

x=20-9

And now we have, x=11

Answer 2

x=11

Explanation:

first solve the things you can simplify on one side of the equation:

4x-3x+9=20--->x+9=20

then, get the variables onto one side of the equation and numbers unto the other.

*minus 9 from each side*

x=11
