Step-by-step explanation:

Alright, so by using the "keep me, change me, turn me over" method - we can easily solve this:

$\frac{8}{9}\div \frac{2}{5}\\=\frac{8}{9}\times \frac{5}{2}\\=\frac{4}{9}\times \frac{5}{1}\\=\frac{4\times \:5}{9\times \:1}\\=\frac{20}{9}$

2(x-3)=3/4(8x-12) step by step please

Umnica [9.8K]

Answer:

$x = \frac{3}{4}$

Step-by-step explanation:

$2(x-3)=\frac{3}{4} (8x-12)$

$2x-6 = \frac{3}{4}8x- \frac{3}{4} 12$

$2x-6 = 6x - 9$

$-6+9 = 6x - 2x$

$3 = 4x$

$x = \frac{3}{4}$
