3x + 12 = 7x - 18
30 = 4x
15/2 or 7.5 or 7 1/2 = x

Step-by-step explanation:

*Whatever you do to one side of the equal sign you must do to the other!

  1. Move the (coefficients?) to one side of the equal sign

2. Get rid of the constant(Notice the negative sign beside the 18. This means you add to get to 0)

3. Separate the number from the variable by dividing because 4x= 4 times x. You must do the inverse operation to get rid of the 4. (Inverse of addition is subtraction, Inverse of subtraction is addition, Divisions multiplication and multiplications division)

Since 4 doesn't go into 30 evenly, I chose to keep it as an improper fraction. If you'd prefer mixed number: 7 2/30

Sorry if it's confusing! Hope I helped! :)

Alborosie
Ok, so she started off with $5.00. 


She bought milk for $2.99.

She buys bread, which costs $1.50. 

Subtracting the money she wasted, the total would be $0.51. 

The only thing she could buy is 5 pieces of gum for 25 cents. 

Her change will be $0.26. 

Hope this helps!

4d^-3 multiplyed by d^18
Verdich [7]
4*d^(-3)*d^18 = 4*d^(18-3) = 4*d^(15).  The trick here is to combine the exponents.

Another way to write this problem would be:

4*d^18
---------- .  Here d^18 divided by d^3 results in d^15, so again the final 
  d^3         answer is 4*d^15.
