Question

5(x+4) +9=13(x+2) Решить уравнение)пжст срочнооо

Answer 1

5(x+4)+9=13(x+2)
5x+20+9=13x+26
5x-13x=26-20-9
-8x=-3
x=-3/-8
x=3/8

Answer 2

5(х+4)+9=13(х+2)
5х+20+9=13х+26
5х-13х=26-20-9
-8х=-3
х=3\8

Answer 3

To solve the equation 5(x+4) + 9 = 13(x+2), we will follow the steps of simplifying and isolating the variable.

Step 1: Distribute the terms

First, we distribute the terms inside the parentheses on both sides of the equation:

5(x+4) + 9 = 13(x+2) 5x + 20 + 9 = 13x + 26

Step 2: Combine like terms

Next, we combine like terms on both sides of the equation:

5x + 29 = 13x + 26

Step 3: Isolate the variable

To isolate the variable, we want to move all terms containing x to one side of the equation. Let's subtract 5x from both sides:

5x - 5x + 29 = 13x - 5x + 26 29 = 8x + 26

Step 4: Solve for x

Now, we can solve for x by subtracting 26 from both sides:

29 - 26 = 8x + 26 - 26 3 = 8x

Finally, we divide both sides by 8 to solve for x:

3/8 = x

Therefore, the solution to the equation 5(x+4) + 9 = 13(x+2) is x = 3/8.
