Answer:
Answer: x is 2
Step-by-step explanation:
[tex]0.3(12x - 16) = 0.4(12 - 3x)[/tex]
open the brackets [ distributive property ]
[tex]3.6x - 4.8 = 4.8 - 1.2x[/tex]
collect like terms together:
[tex]3.6x + 1.2x = 4.8 + 4.8[/tex]
factorise out x :
[tex]x(3.6 + 1.2) = 4.8 + 4.8 \\ 4.8x = 9.6[/tex]
divide by 4.8 on all sides:
[tex] \frac{4.8x}{4.8} = \frac{9.6}{4.8} \\ \\ x = 2[/tex]
