Answer 1

Ответ:

-2х-(-4)= 2х

3х+3=6х

-8х-3=-5х

(5х)^2+25=50х^2

(5х)^2+20х=45х^2

2х-3х+1=1х

Answer 2

Let's solve each of these equations step by step:

4. -2x - (-4) = 3x -2x + 4 = 3x

First, add 2x to both sides of the equation: 4 = 5x

Now, divide both sides by 5 to solve for x: x = 4/5

5. 3x + 3 = 5x

Subtract 3x from both sides of the equation: 3 = 2x

Now, divide both sides by 2 to solve for x: x = 3/2

6. -8x - 3 = -bx

Since there is a variable 'b' involved, we cannot solve this equation for a specific value of x without knowing the value of 'b.'

16. 5x^2 + 25x = 0

Factor out 5x: 5x(x + 5) = 0

Now, you can apply the zero-product property:

1. 5x = 0 x = 0

2. x + 5 = 0 x = -5

So, there are two solutions: x = 0 and x = -5.

17. bx^2 + 24x = 0

Again, we can factor: x(bx + 24) = 0

Now, apply the zero-product property:

1. x = 0

2. bx + 24 = 0 bx = -24

Now, if you know the value of 'b,' you can find the value of x by dividing both sides by 'b':

x = -24/b

18. 5x^2 + 20x = 0

Factor out 5x: 5x(x + 4) = 0

Apply the zero-product property:

1. 5x = 0 x = 0

2. x + 4 = 0 x = -4

So, there are two solutions: x = 0 and x = -4.

19. 2x - 3x + 1 = 0

Combine like terms: -x + 1 = 0

Subtract 1 from both sides of the equation: -x = -1

Now, multiply both sides by -1 to solve for x: x = 1

So, the solution is x = 1.
