Question

2/5(x-5)-1/4(x-2)=9/2​

Answer 1

Answer:

x=73/5

Explanation:

Equation : ( 2/3 ) ( x - 5 ) - 1/4 ( x + 2 ) = 9/ 2

=> { ( 2x - 10 )/ 3 } - { (x + 2)/ 4 } = 9/2

=> { 4( 2x - 10 )/ 12 } - { 3(x + 2)/ 12 } = 9/2

=>  { ( 8x - 40 )/ 12 } - { (3x + 6)/ 12 } = 9/2

=>  { ( 8x - 40 ) - (3x + 6) }/ 12 = 9/2

=>  ( 5x - 46 )/ 12 = 9/2

=>  ( 5x - 46 ) = (9 × 12) / 2

=>  ( 5x - 46 ) = 54/2

=>  ( 5x - 46 ) = 27

=>   5x  = 27 + 46

=>   5x  = 73

=>   x  = 73/5
