Question

8(2.5x-0.75)-0.25(1-x)=0.5

Answer 1

x =
`(1)/(3)`

distribute parenthesis on left side of equation

20x - 6 - 0.25 + 0.25x = 0.5 ( collect like terms on left side )

20.25x - 6.25 = 0.5 ( add 6.25 to both sides )

20.25x = 6.75 ( multiply both sides by 4 )

81x = 27 ( divide both sides by 81 )

x =
`(27)/(81)` =
`(1)/(3)`
