Answer:

x = 8

Explanation:

0.4x - 1.2 = 0.15x + 0.8

Subtract 0.15x from both sides

0.4x - 1.2 -0.15x = 0.15x + 0.8 - 0.15x {Combine like terms}

0.4x - 0.15x - 1.2 = 0.8

0.25x - 1.2 = 0.8 {Add 1.2 to both sides}

0.25x = 0.8 + 1.2

0.25x = 2.0 {Divide both sides by 0.25}

x = 2/0.25

$x=(2*100)/(0.25*100)\\\\x=(200)/(25)\\\\x=8$
