7 Попробуй решить уравнения.8/100+x=34/100+56/10060/90-(6/90+x)=29/90 Помогите​

Answer 1

Пошаговое объяснение:

8/100+х=34/100+56/100

0,08+х=0,34+0,56

0,08+х=0,9

Х=0,9-0,08

Х=0,82

60/90-(6/90+х)=29/90

60/90-6/90-х=29/90

54/90-х=29/90

-х=29/90-54/90

-х= - 25/90

Х=25/90=5/18

Answer 2

Solving the Equations

To solve the given equations, let's start with the first equation:

Equation 1: 8/100 + x = 34/100 + 56/100

First, we can simplify the right-hand side of the equation by adding 34/100 and 56/100, which equals 90/100 or 0.9. So, the equation becomes:

8/100 + x = 0.9

To solve for x, we can subtract 8/100 from both sides:

x = 0.9 - 8/100 x = 0.9 - 0.08 x = 0.82

Now, let's move on to the second equation:

Equation 2: 60/90 - (6/90 + x) = 29/90

First, we can simplify the left-hand side of the equation by adding 60/90 and -6/90, which equals 54/90 or 0.6. So, the equation becomes:

0.6 - (6/90 + x) = 29/90

To solve for x, we can start by simplifying the expression inside the parentheses:

0.6 - 6/90 - x = 29/90 0.6 - 6/90 - x = 29/90

Next, we can combine the constants on the left-hand side:

0.6 - 6/90 - x = 29/90 0.6 - 0.0667 - x = 0.3222 0.5333 - x = 0.3222

Finally, we can solve for x by subtracting 0.5333 from both sides:

-x = 0.3222 - 0.5333 -x = -0.2111 x = 0.2111 (after multiplying both sides by -1)

So, the solution to the second equation is x = 0.2111.

Therefore, the solutions to the given equations are: - Equation 1: x = 0.82 - Equation 2: x = 0.2111
