Solve 1510x 25 1420x 8Solutiongiven 1510x 25 1420x 8 tak

Solution

given

1/5(10x -25) = 1/4(20x -8)

take 1/5 to the right hand side & bring the 1/4 to the left hand side

4( 10x - 25 ) = 5(20x - 8)

now multiply in brackets

4(10x) - 4(25) =5(20x) -5(8)

40x -100 = 100x -40

40x -100x = -40 + 100

-60x = 60

x=-1 --->ANSWER

so the value of x=-1 for 1/5(10x -25) = 1/4(20x - 8)
