Question

0,5(х-4)=0,4(8-х)-1,6?​

Answer 1

Ответ:

$0,5(x-4)=0,4(8-x)-1,6\\0,5x-2=3,2-0,4x-1,6\\0,5x+0,4x=2+3,2-1,6\\0,9x=3,6\\x=3,6:0,9\\x=4$

Answer 2

To solve the equation 0.5(x-4) = 0.4(8-x) - 1.6, you'll want to simplify and isolate the variable x. Here's how you can do that step by step:

1. Distribute the numbers inside the parentheses: 0.5x - 2 = 3.2 - 0.4x - 1.6

2. Combine like terms on both sides of the equation: 0.5x + 0.4x = 3.2 - 1.6 + 2

3. Add and subtract the numbers on the right side: 0.9x = 1.6

4. Finally, solve for x by dividing both sides by 0.9: x = 1.6 / 0.9 x ≈ 1.7778

So, the solution to the equation is approximately x ≈ 1.7778.
