Answer 1

Ответ:

Пошаговое объяснение:

4x-2=24,5

4х=24.5+2

4х=26.5

х=26.5:4

х=6.625

3+5x+2,1=0,7

5х=0.7-2.1-3

5х=-4.4

х=-4.4:5

х=-0.88

3x+2,7-4=0,2

3х=0.2+4-2.7

3х=1.5

х=1.5:3

х=0.5

Answer 2

It seems like you've written three equations with variables. Let's solve each of them one by one:

1. 4x - 2 = 24.5 To solve for x, first, add 2 to both sides of the equation: 4x - 2 + 2 = 24.5 + 2 4x = 26.5

Now, divide both sides by 4 to isolate x: 4x/4 = 26.5/4 x = 6.625

So, the solution to the first equation is x = 6.625.

2. 53 + 5x + 2.1 = 0.7 To solve for x, first, subtract 53 and 2.1 from both sides of the equation: 5x = 0.7 - 53 - 2.1 5x = -54.4

Now, divide both sides by 5 to isolate x: 5x/5 = -54.4/5 x = -10.88

So, the solution to the second equation is x = -10.88.

3. 3x + 2.7 - 4 = 0.2 To solve for x, first, add 4 to both sides of the equation: 3x + 2.7 - 4 + 4 = 0.2 + 4 3x + 2.7 = 4.2

Now, subtract 2.7 from both sides to isolate 3x: 3x + 2.7 - 2.7 = 4.2 - 2.7 3x = 1.5

Finally, divide both sides by 3 to find x: 3x/3 = 1.5/3 x = 0.5

So, the solution to the third equation is x = 0.5.
