DExpressions and Equations Interactive Study guide:
A:first you add 5x and 9x together and then you subtract2 from -236. and your final answer would be 14x +(-234).
B.first you multiply the recisprocal of -3/4 by3x/8 and 1/6. your final answer should be 2x plus 4/18.
c.first you add 2.3x to 4.2. then y7.5x -10.26 as your final answer.
D.first you subtract 7/12 from both sides of the equation,but then you have to fina a common denominator between both fractions before you can subtract. then you did your answer(from7/12-7/8) and divide by3/4.
For the equations, remember you are solving for x. So for letter A, you would have -14x EQUAL -238 and then divide by -14. Your goal for these problems is to isolate x so that it is by itself.
For problems B and D, don't forget to find a common denominator. For example, letter B has a common denominator of 24. You would want to multiply all terms by 24.
