Question

3x-1=2(x-2) 25-4x= 12-5x

Answer 1

Ответ:

Пошаговое объяснение:

1) 3х-1=2х-4

3х-2х=-4+1

Х=-3

2) -4х+5х=12-25

х=-13

Answer 2

Let's solve each equation step by step:

1. 3x - 1 = 2(x - 2)

To solve this equation, distribute the 2 on the right side:

3x - 1 = 2x - 4

Now, let's isolate the variable x by moving all the x terms to one side and the constant terms to the other side:

3x - 2x = -4 + 1

x = -3

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

2. 25 - 4x = 12 - 5x

Similarly, let's isolate the variable x by moving all the x terms to one side and the constant terms to the other side:

25 - 12 = -5x + 4x

13 = -x

To get the value of x, we need to multiply both sides by -1 (to remove the negative sign):

x = -13

So, the solution for the second equation is x = -13.

Therefore, the solutions for the two equations are:

1. x = -3
2. x = -13
