What will you get if you do this

4x-3x+9=20

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*

x=11

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :
