1. We first simplify both sides of the equation, factoring the parentheses and adding like numbers:
Then, we move all the Xs to one side and all the numbers to the other by subtracting 3x from both sides and adding 3 to both sides:
We get x = 4.
2. First, we simplify:
Then, we try to move the Xs to one side, but we get 13x - 13x, which equals 0x. This problem is impossible, as it states 45 = 10.
