Simplify the following expression.
34kurt

Answer:

A. 33x + 92y

Step-by-step explanation:

Set up the problem like this and combine like terms:

    40x + 58y

   - 7x  + 34y

--------------------

    33x + 92y

Or, set up the problem like this and combine like terms:

(40x + 58y) + (-7x + 34y)

40x + 58y - 7x + 34y

40x - 7x + 58y + 34y

33x + 92y

You should get the same answer with either method.

X + 9 = 18 + -2x what does x epual
babymother [125]

Answer:

x = 3

Step-by-step explanation:

Step 1: Write out equation

x + 9 = 18 - 2x

Step 2: Add 2x on both sides

x + 2x + 9 = 18 - 2x + 2x

3x + 9 = 18

Step 3: Subtract 9 on both sides

3x + 9 - 9 = 18 - 9

3x = 9

Step 4: Divide both sides by 3

3x/3 = 9/3

x = 3
