Respuesta :
0.2(x + 20) - 3 > -7 - 6.2x.....distribute trhr the parenthesis
0.2x + 4 - 3 > -7 - 6.2x...simplify
0.2x + 1 > - 7 - 6.2x...addition property...add 6.2x to both sides
0.2x + 6.2x + 1 > -7 ...simplify
6.4x + 1 > - 7.....subtraction property....subtract 1 from both sides
6.4x > -7 - 1....simplify
6.4x > -8....division property....divide both sides by 6.4
x > -8 / 6.4...simplify
x > - 1.25 <==

0.2x+4-3>-7-6.2x
0.2x+1>-7-6.2x
0.2x+0.6x>-8
0.8x>-8
the correct answer is: x>-1.25
