Need help with solving this equation
0.3x + 9 <= 0.7x - 8
..
add -0.7x to both sides
0.3x-0.7x<=-8
-0.4x<=-8
/-0.04
x>=8

0.3x+%2B+9+%3C=+0.7x+-+8
0.3x+%2B+9%3C=+0.7x+-+8.......add -9 to both sides
0.3x+%2B+9+-+9+%3C=+0.7x+-+8+-+9

0.3x+%2Bcross%28+9%29+-+cross%289%29+%3C=++0.7x+-+17

0.3x++%3C=++0.7x+-+17......add -0.7x to both sides
0.3x+-+0.7x++%3C=++cross%280.7x%29+-+cross%280.7x%29+-+17

-0.4x++%3C=+++-+17.......both sides multiply by -1
-0.4x%2A%28-1%29++%3C=+++-+17%2A%28-1%29

0.4x+%3C=+17
x+%3C=+17%2F0.4
x+%3C=+42.5
