Question

2a + 7 = 13в - 4в = 5x + 6 + 2x = 14в + 5a +2в +a =

Answer 1

Пошаговое объяснение:

2a + 7 =  2а+7

13в - 4в =  9в

5x + 6 + 2x =  7х+6

14в + 5a +2в +a = 6а+16в

Answer 3

To solve this system of equations, let's take it one step at a time. We'll name each equation for reference:

1. $2a + 7 = 13$

This equation is straightforward to solve:

Subtract 7 from both sides:

$2a = 6$

Divide both sides by 2:

$a = 3$

2. $в - 4в = 5x + 6 + 2x$

Combine like terms:

$-3в = 7x + 6$

Divide both sides by -3:

$в = -\frac{7}{3}x - 2$

3. $14в + 5a + 2в + a$

Substitute the value of $a$ from equation 1:

$14в + 5(3) + 2в + 3$

Simplify:

$14в + 15 + 2в + 3$

Combine like terms:

$16в + 18$

$= 2(8в + 9)$

So, the expression $14в + 5a + 2в + a$ simplifies to $2(8в + 9)$.
