<span>An
algebra test had two parts.
=> Part I had 40 problems
=> and part II had 60 problems.
Bernard got 80% of the problems on part I correct and 90% of the problems on
part II correct. What was the total number of problems that Bernard got correct
on the test.
Part 1
=> 40 problems and Bernard was able to answer correctly that 80% of it
=> 40 * .80 = 32 questions are correct
Part 2
=> 60 problems and Bernard was able to answer correctly the 90% of it.
=> 60 * .90 = 54 questions got correct answers.</span>

So, what we're doing here is solving for x. We must isolate x to find it's value.
Here's how:
17 = 12(x + 2) + 2x
First, we'll distribute the 12
17 = 12*x + 12*2 + 2x
17 = 12x + 24 + 2x
Combine like terms
17 = 14x + 24
Then, we'll subtract 24 from both sides.
17 - 24 = 14x + 24 - 24
-7 = 14x
Then, to isolate x, we'll divide both sides by 14
-7/14 = x
x = -1/2
