Answer:
x>-60
Step-by-step explanation:
Group like terms: 0.6x + x +12 > 2x+6-0.5x
add similar elements: (0.bx + x=1.6x) 1.6x + 12 >2x + 6 -0.5x
group like terms: 1.6x+ 12 > 2x-0.5x+6
add similar elements:(2x-0.5x=1.5x) 1.6x+12>1.5x+6
multiply both sides by 10:1.6x*10+12*10>1.5x*10+6*10
refine:16x+120>15x+60
subtract 120 from both sides:16x+120-120>15x+60-120
simplify:16x>15x-60
subtract 15x from both sides:16x-15x>-60-15x
simplify(which get's you answer)
