Question

7×(3х +26)+84=413 решить уравнение

Answer 1

21x+182+84=413
21x=413-182-84
21x=147
x=7

Answer 2

To solve the equation 7×(3x + 26) + 84 = 413, we will follow these steps:

1. Begin by simplifying the equation: 7 × (3x + 26) + 84 = 413 Distribute the 7 to the terms inside the parentheses: 21x + 182 + 84 = 413 Combine like terms: 21x + 266 = 413

2. Move the constant term to the other side of the equation by subtracting 266 from both sides: 21x + 266 - 266 = 413 - 266 21x = 147

3. Divide both sides of the equation by 21 to isolate x: (21x)/21 = 147/21 x = 7

Therefore, the solution to the equation is x = 7.
