### Grade 8 - Mathematics1.5 Equations With Fractional Coefficients - II

 Example: Solve the equation 5x/3 + 7/2 = 4. Solution: L.C.M. of denominators 3 and 2 is 6. Multiplying both sides of the equation by 6 we get, 6*5x/3 + 6*7/2 = 6*4. 10x+21 = 24 10x = 24-21 10x = 3 x = 3/10 Verification: Substitute x = 3/10 in the equation. L.H.S.Þ5x/3 + 7/2 = 5/3*3/10 + 7/2 = 1/2 + 7/2 Þ(1+7)/2 = 8/2 = 4 = R.H.S. \ x = 3/10 is the solution. Directions: Solve the following problems. Also write at least 5 equations with fractional coefficients of your own and solve them.
