Question

1) 12х-3=6х+3 2) 25х+18=13х+6

Answer 1

Пошаговое объяснение:

$12x - 3 = 6x + 3 \\ 12x - 6x = 3 + 3 \\ 6x = 6 \\ x = 1$

$25x + 18 = 13x + 6 \\ 25x - 13x = 6 - 18 \\ 12x = - 12 \\ x = - 1$

Answer 2

Sure, I can help you solve these equations. Let's start with the first one:

1. 12x - 3 = 6x + 3

To solve this equation, you want to isolate the variable x on one side of the equation. Here's how you can do it step by step:

First, you can simplify the equation by moving all terms involving x to one side and constants to the other side:

12x - 6x = 3 + 3

Now, perform the arithmetic operations on both sides of the equation:

6x = 6

To isolate x, divide both sides by 6:

(6x) / 6 = 6 / 6

x = 1

So, the solution to the first equation is x = 1.

Now, let's move on to the second equation:

2. 25x + 18 = 13x + 6

Similarly, we'll isolate x on one side:

First, subtract 13x from both sides of the equation to move all terms involving x to the left side:

25x - 13x + 18 = 6

Combine like terms on the left side:

12x + 18 = 6

Next, subtract 18 from both sides to isolate the 12x term:

12x + 18 - 18 = 6 - 18

12x = -12

Now, divide both sides by 12 to find the value of x:

(12x) / 12 = (-12) / 12

x = -1

So, the solution to the second equation is x = -1.
