Question

0,5-5(4-2,3×)=10,4×+8

Answer 1

Ответ:

0,5-5(4-2,3×)=10,4×+8

0,5-20+11,5х=10,4х+8

-19.5+11,5х=10,4х+8

11,5х-10,4х=8+19,5

1,1х=27.5

х=25

Answer 2

To solve the equation, let's break it down step by step:

0.5 - 5(4 - 2.3×) = 10.4× + 8

First, let's simplify the expression within the parentheses:

0.5 - 5(4 - 2.3×) = 10.4× + 8 0.5 - 20 + 11.5× = 10.4× + 8

Next, let's simplify the left-hand side by combining like terms:

-19.5 + 11.5× = 10.4× + 8

Now, let's gather the terms with × on one side of the equation and the constant terms on the other side:

11.5× - 10.4× = 8 + 19.5 (11.5 - 10.4)× = 27.5 1.1× = 27.5

Finally, let's solve for × by dividing both sides of the equation by 1.1:

1.1× / 1.1 = 27.5 / 1.1 × = 25

Therefore, the solution to the equation is × = 25.
