Solve for x. (1/4)(5x−3) > (1/2)x + (1/3)

svet-max [94.6K]

Answer:

x >13/9

Step-by-step explanation:

(1/4)(5x−3) > (1/2)x + (1/3)

Distribute

5/4x - 3/4 > 1/2x + 1/3

Multiply each side by 12 to get rid of fractions

12*5/4x -12* 3/4 >12* 1/2x +12* 1/3

15x -9 > 6x +4

Subtract 6x from each side

15x-6x-9 > 6x-6x+4

9x -9> 4

Add 9 to each side

9x-9+9 > 4+9

9x > 13

Divide by 9

9x/9 >13/9

x >13/9
