Multiply each term by 30:
10(2x-5) - 15(3) = 6(x+4)
20x - 50 - 45 = 6x + 24
20x - 95 = 6x + 24
20x - 6x = 24 + 95
14x = 119
x = 119/14 = 8.5.

(2x – 5)/3 – 3/2 = (x + 4)/5 (x 5)
5(2x – 5)/3 – 5*3/2 = (x + 4)
5(2x – 5)/3 – 15/2 = (x + 4) (x 2)
2*5(2x – 5)/3 – 2*15/2 = 2(x + 4)
10(2x – 5)/3 – 15 = 2(x + 4) (x 3)
3*10(2x – 5)/3 – 3*15 = 3*2(x + 4)
10(2x – 5) – 45 = 6(x + 4)
20x - 50 - 45 = 6x + 24
20x - 95 = 6x + 24
20x - 6x = + 24 + 95
14x = 119
x = 119/14
x = 8â5

Multiply the entire equation through by the LCM of 3, 2, & 5 which is 30. This will give you:
10(2x-5) - 3(15) = 6(x+4)
Remove parentheses:
20x - 50 - 45 = 6x + 24
Combine like terms on left side of equation:
20x - 95 = 6x + 24
Add 95 to both sides of the equation:
20x = 6x + 119
Subtract 6x from both sides of the equation:
14x = 119
Divide by 14:
x = 8 1/2

(2x-5)/3 - 3/2=(x+4)/5 multiply everything with 30
30*[(2x-5)/3] - 30*(3/2)=30*[(x+4)/5]
10(2x-5) - 15*3=6(x+4)
10*2x-5*10 - 45=6x+24
20x-50-45=6x+24
20x-6x=24+50+45
14x=119
(14x)/14=119/14
x=8,5

multipy all in 30
then we have :
10(2x-5)-45=(x+4)6
so we have :
20x-50-45=6x+24
and we have :
14x=119
and x= 17/2 or 8.5

(2x-5)/3-3/2=(x+4)/5
10(2x-5)-45=6(x+4)
20x-50-45=6x+24
20x-6x=24+50+45
14x=119
x=8.5

my hint:
multiply each term by 3. then multiply each term by 2. then multiply each term by 5.
when all is said and done, it should look like a much easier problem.
