QUESTION: Solve the equation 5x+18=2-3x.

 

ANSWER: We want the x terms on one side. So, adding 3x to both sides, we get

8x+18=2

Then, subtracting 18 from both sides, we get

8x=-16

Finally, dividing both sides by 8, we get

x=\dfrac{-16}{8}=-2

Note: it’s possible to take a different route but get to the same answer. As long as your steps are mathematically correct, and your answer is -2, then you get full marks.
