This is simply is double check question
does 7 - 2a/3 - a-5/12 + 3(a+3)/2 < a - 3/4(2a-7) + 5a-1/6 simplified = -3 19/21 ? show all work
7 - 2a/3 - a- 5/12 + 3(a+3)/2 < a - 3/4(2a-7) + 5a-1/6
7 - (2/3)a - a - (5/12) + (3/2)(a + 3) < a - (3/4)(2a - 7) + 5a - (1/6)
7 - (2/3)a - a - (5/12) + (3/2)a + (9/2) < a - (3/2)a + (21/4) + 5a - (1/6)
Multiply through by 12
84 - 8a - 12a - 5 + 18a + 54 < 12a - 18a+ 63 + 60a - 2
133 - 2a < 54a + 61
72 < 56a divide by 56
72/56 < a
a > 9/7
