Answer 2

Solve for x by simplifying both sides of the equation, then isolating the variable.

x/2 + 3x/4 + 5x/6 = 21

LCM = 12, then multiple on both sides

12[x/2 + 3x/4 + 5x/6 = 21]12

6x + 9x + 10 x = 252

25x = 252

x = .......

Exact Form:

x = 252/25

Decimal Form:

x = 10.08

Mixed Number Form:

x = 10 2/25
