Question

Решите уравнение
$( frac{3}{4} x- frac{2}{3} )*15=8$

Answer 1

$(frac{3*3x}{12} - frac{4*2}{12} )*15=8 \ frac{9x-8}{12}*15=8 \ frac{(9x-8)*5}{4} =8 \ frac{45x-40}{4} =8$

45x-40=8*4
45x=32+40
45x=72
x=1,6

Answer 2

(3/4х - 2/3) * 15 = 8
45/4х - 30/3 = 8
11,25х - 10 = 8
11,25х = 8 + 10
11,25х = 18
х = 18 : 11,25
х = 1,6
