Question

(7x+24):13+71=74 чему = x

Answer 1

Решение:

(7x + 24) : 13 + 71 = 74

(7x + 24) : 13 = 74 - 71

(7x + 24) : 13 = 3

7x + 24 = 3 * 13

7x + 24 = 39

7x = 39 - 24

7x = 15

x = 15 : 7

$\tt\displaystyle x = 2\frac{1}{7}$

Answer 2

To find the value of x, we can solve the equation step-by-step:

(7x + 24) / 13 + 71 = 74

Step 1: Subtract 71 from both sides of the equation to isolate the term with x.

(7x + 24) / 13 = 74 - 71

Step 2: Simplify the right side.

(7x + 24) / 13 = 3

Step 3: To eliminate the fraction, multiply both sides of the equation by 13.

13 * (7x + 24) / 13 = 3 * 13

Step 4: Simplify both sides.

7x + 24 = 39

Step 5: Now, isolate the term with x by subtracting 24 from both sides.

7x = 39 - 24

Step 6: Simplify the right side.

7x = 15

Step 7: Finally, to find the value of x, divide both sides by 7.

x = 15 / 7

x ≈ 2.14

So, x is approximately equal to 2.14.
