А)х=-3
Б)х=8
С)х=5
Д)х=-5

Answer 3

Let's solve each equation step by step:

a) N225a 14x - 426 = 0:

To solve for x, we can isolate the term with x on one side of the equation and simplify:

14x - 426 = 0 14x = 426 x = 426/14 x ≈ 30.43

Therefore, the solution for equation a) is x ≈ 30.43.

b) 2x - 16 = 0:

Again, isolate the term with x on one side of the equation:

2x - 16 = 0 2x = 16 x = 16/2 x = 8

So, the solution for equation b) is x = 8.

c) 8x - 17 = 23:

Isolate the term with x:

8x - 17 = 23 8x = 23 + 17 8x = 40 x = 40/8 x = 5

Hence, the solution for equation c) is x = 5.

d) 5 - x = 20 + 2x:

First, simplify the equation:

5 - x = 20 + 2x

Let's move the terms with x to one side of the equation:

5 + x = 20 + 2x

Now, we'll move the constant terms to the other side:

x - 2x = 20 - 5

Simplifying further:

-x = 15

Multiply both sides of the equation by -1 to solve for x:

(-1)(-x) = (-1)(15) x = -15

Thus, the solution for equation d) is x = -15.

To summarize: a) x ≈ 30.43 b) x = 8 c) x = 5 d) x = -15
