Answer:

x +  \frac{2}{3} - x +  \frac{1}{5}  = x -  \frac{3}{4}  - 1

 \frac{3x + 2}{3}   -  \frac{5x + 1}{5}  =  \frac{4x - 3}{4}  - 1

 \frac{15x + 10 - 15x - 3}{15}  =  \frac{4x - 3 - 4}{4}

15x and -15x are cancelled

 \frac{10 - 3}{15}  =  \frac{4x - 3 - 4}{4}

 \frac{7}{15}  =  \frac{4x - 7}{4}

15(4x - 7) = 7 \times 4

cross multiplying the equation.

60x - 105 = 28

-108 becomes +108 because of changing its side.

60x = 28 + 108

60x = 136

x =  \frac{136}{60}

x = 2.27

Hope it helps u...

Appropriate Question :-

Solve :  \rm \frac{x + 2}{3}  -  \frac{x + 1}{5} =  \frac{x - 3}{4}   - 1 \\

Answer :-

  • 19

Step by step explanation :-

\rm:\longmapsto{ \frac{x + 2}{3}  -  \frac{x + 1}{5}  =  \frac{x - 3}{4} - 1 } \\

By LCM

\rm:\longmapsto{ \frac{5(x + 2) - 3(x + 1)}{3 \times 5} =  \frac{x - 3 - 4}{4}  } \\  \\ \rm:\longmapsto{ \frac{5x + 10 - 3x - 3}{15} =   \frac{x - 7}{4}  } \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\\rm:\longmapsto{ \frac{2x + 7}{15}  =  \frac{x - 7}{4} } \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\\rm:\longmapsto{15(x - 7) = 4(2x} + 7) \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\\rm:\longmapsto{15x - 105 = 8x + 28}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \:   \:  \:  \:  \:  \:  \:  \:  \\  \\ \rm:\longmapsto{15x - 8x = 28 + 105} \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\\rm:\longmapsto{7x = 133} \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  \\ \rm:\longmapsto{x =  \frac{133}{7} } \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \\  \\ \bf:\longmapsto \red{x = 19} \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:
