Question

-0,9(1,2-×)=0,8(×+2,4)

Answer 1

.......................

Answer 2

0,9(1,2-х)=0,8(х+24)

1,08-0,9х=0,8х+19,2

-0,9х-0,8х=19,2-1,08

-1,7х=18,12

х=-906/85

х= 10 56/85

Answer 3

Let's solve the equation step by step:

1. Distribute the terms on the right side: 0.8(× + 2.4) = 0.8× + 0.8(2.4) = 0.8× + 1.92

2. Expand the left side: -0.9(1.2 - ×) = -0.9 * 1.2 + 0.9× = -1.08 + 0.9×

Now the equation becomes: -1.08 + 0.9× = 0.8× + 1.92

3. Move the variable terms (with ×) to one side and constant terms to the other side: 0.9× - 0.8× = 1.92 + 1.08

4. Combine like terms: 0.1× = 3

5. Solve for × by dividing both sides by 0.1: × = 3 / 0.1 × = 30

So the solution to the equation is × = 30.
