Answer is option 4. working out attached
hope it helps :)
70/3
6x > 220 - 80
220 - 80 = 140
6x > 140
Divide 6 on all terms & simplify.
6x/6 > 140/6
Divide x by 1 and cancel common factor 140/6
x > 140/6
Factor 2 out of 140
x > 2(70) / 6
Cancel common factors
Factor 2 out of 6
x > 2 • 70 / 2 • 3
Cross out both of the 2’s and rewrite expression
x > 70/3 or (70/3 , ♾ )
