Answer: x>15

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality:

(56/10)+(22/10)*x-((656/10)-(18/10)*x)>0

Simplify 9/5

56 22 656 9

(——+(——•x))-(———-(—•x)) > 0

10 10 10 5

Simplify 328/5

56 22 328 9x

(——+(——•x))-(———-——) > 0

10 10 5 5

Adding fractions which have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

328 - (9x) 328 - 9x

—————————— = ————————

5 5

56/10+22/10.x/5)) >0 (328 - 9x)

Simplify 11/5

56/10+11/5.x/5))->0 (328-9x

Simplify 28/5

28 11x (328 - 9x)

(—— + ———) - —————————— > 0

5 5 5

Adding fractions which have a common denominator

Adding fractions which have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

28 + 11x 11x + 28

———————— = ————————

5 5

:

(11x + 28) (328 - 9x)

—————————— - —————————— > 0

5 5

Adding fractions which have a common denominator

Adding fractions which have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

(11x+28) - ((328-9x)) 20x - 300

————————————————————— = —————————

5 5

Pull out like factors :

20x - 300 = 20 • (x - 15)

20 • (x - 15)

————————————— > 0

Multiply both sides by 5

Divide both sides by 20

Solve Basic Inequality :

Add 15 to both sides

x > 15
