3/2x + 1/5x = 11/6x - 2/15....to get rid of fractions, multiply by common denominator, which is 30.

45x + 6x = 55x - 4
51x = 55x - 4
51x - 55x = -4
-4x = -4
x = -4/-4
x = 1

1. 30 • 3/2x + 30 x 1/5x = 30 • 11/6x - 30 • 2/15

(To simplify, multiply both sides by the least common denominator)

2. 15 • 3x + 6x = 5 • 11x - 2 • 2

(Multiply)

3. 45x + 6x = 55x - 4

(Collect Like Terms)

4. 51x = 55x - 4

(Move variable to the left side and change its sign)

5. -4x = -4

(Divide both sides of the equation by -4)

6. x = 1

How to solve for literal equations with multiple variables

myrzilka [38]

<span>See examples for the method to solving literal equations for a given variable: Solve A = bh for b. Since h is multiplied times b, you must divide both sides by h in order to isolate b. Since (c+d) is divided by 2, you must first multiply both sides of the equation by 2</span>
