Answer:
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
x=11
Step-by-step 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*
