Answer 2

Answer:

Answer: x is 2

Step-by-step explanation:

$0.3(12x - 16) = 0.4(12 - 3x)$

open the brackets [ distributive property ]

$3.6x - 4.8 = 4.8 - 1.2x$

collect like terms together:

$3.6x + 1.2x = 4.8 + 4.8$

factorise out x :

$x(3.6 + 1.2) = 4.8 + 4.8 \\ 4.8x = 9.6$

divide by 4.8 on all sides:

$\frac{4.8x}{4.8} = \frac{9.6}{4.8} \\ \\ x = 2$
