Answer 1

В) я тебе решить не смогу, равно даже нет.
А)х-8.2+3.8=15.6
х-4.4=15.6
х=20
б)34.3-17.9+y=22
16.4+y=22
y=5.6
г) r+16.23-15.8=71
r+0.43=71
r=70.57

Answer 2

Solving Equations

Sure, I can help you solve these equations. Let's go through each one step by step:

a) Equation: X - 8.2 + 3.8 = 15.6

To solve this equation, we need to isolate the variable X. Let's start by simplifying the equation:

X - 4.4 = 15.6

Next, we can isolate X by adding 4.4 to both sides of the equation:

X = 15.6 + 4.4

Simplifying further, we get:

X = 20

So the solution to the equation is X = 20.

b) Equation: 34.3 - (17.9 - у) = 22

To solve this equation, we need to simplify the expression inside the parentheses first:

34.3 - 17.9 + у = 22

Next, we can combine like terms:

16.4 + у = 22

To isolate у, we subtract 16.4 from both sides of the equation:

у = 22 - 16.4

Simplifying further, we get:

у = 5.6

So the solution to the equation is у = 5.6.

c) Equation: 61.5 - (t + 3.4) + 4.9

To solve this equation, we need to simplify the expression inside the parentheses first:

61.5 - t - 3.4 + 4.9

Next, we can combine like terms:

62 - t + 4.9

To isolate t, we subtract 4.9 from both sides of the equation:

62 - 4.9 = t

Simplifying further, we get:

t = 57.1

So the solution to the equation is t = 57.1.

г) Equation: r + 16.23 - 15.8 = 71

To solve this equation, we need to simplify the expression:

r + 0.43 = 71

To isolate r, we subtract 0.43 from both sides of the equation:

r = 71 - 0.43

Simplifying further, we get:

r = 70.57

So the solution to the equation is r = 70.57.

I hope this helps! Let me know if you have any further questions.
