Пошаговое объяснение:

а) х+19-25=-8

х= -8-19+25

х= -2

б) 10-х-4=-2

-х=-2-10+4

-х=-8

х=8

в) 10-х+35-70=8

-х=8-10-35+70

-х=33

х=-33

Answer 3

Sure, let's solve these equations:

A)

1. x + 19 - 25 = -8

First, combine like terms on the left side:

x - 6 = -8

2. Now, isolate x by adding 6 to both sides of the equation:

x - 6 + 6 = -8 + 6

x = -2

So, the solution for equation A is x = -2.

B)

1. 40 - x + 35 - 70 = 8

Combine like terms on the left side:

(40 + 35) - (x + 70) = 8

75 - (x + 70) = 8

2. Now, isolate the expression (x + 70) by subtracting 75 from both sides of the equation:

75 - (x + 70) - 75 = 8 - 75

-x - 70 = -67

3. Finally, isolate x by adding 70 to both sides of the equation:

-x - 70 + 70 = -67 + 70

-x = 3

Now, to get the value of x, multiply both sides by -1 to isolate x:

(-1)(-x) = 3(-1)

x = -3

So, the solution for equation B is x = -3.
