This week I had quite a bit of difficulty on the skills check, especially with the equation on the back:
However, while doing corrections I had a huge “Ah-Ha!” moment, and the solution made itself clear to me. My first try was a disaster:
I got rid of the brackets with multiplication.
Then, I added to the equation in order to remove the fraction on the left side.
I multiplied the equation by 3 to turn into 4x and into 2.
Then I ran out of time…but clearly I had no clue what I was doing. Even if I did finish, the answer probably would have been wrong. My second try makes much more sense:
I multiplied 2x and -1 by .
I multiplied everything by 3.
I added +2 to both sides.
I multiplied the equation by 2.
I subtracted 3x from both sides.
After dividing the equation by 5, I got the answer!
x = -10
