1. 10k – 6 = 14 2. 3. 15 – 2b = -9 4. 2d + 10 = 6d – 10 5. –2a – 9 = 6a + 15 7. What would be the 1st step to solving the equation below? 30 + 0.50x = 1.25x A subtract 30 from both sides B subtract 0.50x from both sides C add 0.50x to both sides D add 30 to both sides 8. At what step was the first mistake made? A Step 1 B Step 2 C Step 3 D Step 4 6. X + 24 = 12 + 3x

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 :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

7 is the median   7.875 is the mean
