Each problem in this problem set looks like 2/5 * x + 3 = 9 or 2 + 7/8 * x = 44 or 5/6 * x - 3 = 52. The first step is to 'undo' the addition or subtraction and the second step is to solve the fraction portion of the equation.
Solve 2/5 * x + 3 = 9 2/5 * x + 3 - 3 = 9 - 3 which becomes 2/5 * x = 6 which becomes (2/5) * (5/2) * x = 6 * (5/2) which becomes x = 30/2 which becomes x = 15.
Solve 5/6 * x - 3 = 52 5/6 * x - 3 + 3 = 52 + 3 becomes 5/6 * x = 55 which becomes (5/6) * (6/5) * x = 55 * (6/5) which becomes x = 330/5 which becomes x = 66.
Solve 3/20 * x + 4 = 7 3/20 * x + 4 - 4 = 7 - 4 becomes 3/20 * x = 3 which becomes (20/3) * (3/20) * x = 3 * (20/3) which becomes x = 60/3 which becomes x = 20.
For each problem in this problem set you will need to solve each equation. Strive to be able to accomplish solving the equations with ease and then strive for increasing your speed. Good luck and enjoy the challenge!
