Question

28(1-4х)=7 решите плиз

Answer 1

Ответ:

$x=\frac{3}{16}$

Пошаговое объяснение:

$28(1-4x)=7\\28-112x=7\\-112x=7-28\\-112x=-21\\112x=21\\x=\frac{21}{112} =\frac{3}{16}$

$28(1-4*\frac{3}{16} )=28(1-\frac{3}{4} )=28*(\frac{4}{4} -\frac{3}{4} )=28*\frac{1}{4} =7$

7=7

Answer 2

Ответ:

$\frac{3}{16}$

Пошаговое объяснение:

1-4х= $\frac{7}{28}$

4х= 1 - 7/28

4х= $\frac{21}{28}$= $\frac{3}{4}$

х=$\frac{3}{4}$ / $\frac{16}{4}$= 3·4/16·4 =$\frac{3}{16}$

Answer 3

Sure, I'd be happy to help you solve the equation.

28(1 - 4x) = 7

Let's solve it step by step:

1. Distribute the 28 on the left side of the equation:

28 - 112x = 7

2. Now, let's isolate the term with x on one side of the equation. To do that, we want to get rid of the constant term (7) on the right side. We can do this by subtracting 7 from both sides of the equation:

28 - 112x - 7 = 7 - 7

3. Simplify the equation:

21 - 112x = 0

4. Now, isolate the term with x on one side by getting rid of the constant term (21) on the left side. We can do this by subtracting 21 from both sides:

21 - 112x - 21 = 0 - 21

5. Simplify the equation:

-112x = -21

6. Finally, to find the value of x, divide both sides by -112:

x = -21 / -112

x = 0.1875

So, the solution to the equation is x = 0.1875.
