3(5X - 2) = 54

3*5X - 3*2 = 54

15X - 6 = 54

15X = 60

X = 60/15 = 4

∴ X = 4

-5 + X = -21

X = -21 + 5 = -16

∴ X = -16

7 - 4X > 3 - 3X

-4X + 3X > 3 - 7

-X > -4

The inequality sign (>) becomes (<) when multiplying -1 LHS and RHS.

∴ X < 4

3*5X - 3*2 = 54

15X - 6 = 54

15X = 60

X = 60/15 = 4

∴ X = 4

-5 + X = -21

X = -21 + 5 = -16

∴ X = -16

7 - 4X > 3 - 3X

-4X + 3X > 3 - 7

-X > -4

The inequality sign (>) becomes (<) when multiplying -1 LHS and RHS.

∴ X < 4
