Question

1,2(3b+5)=2(2,4b-3,6)​

Answer 1

Ответ:

1,2(3b+5)= 2(2.4b-3.6)

3.6b +6=4.8b-7.2

3.6b-4.8b= -6-7.2

-1.2b=-13,2

b=-13,2:-1,2

b= 11

Пошаговое объяснение:

Answer 2

1,2(3b+5)=2(2,4b-3,6);

3,6b+6=4,8b-7,2;

3,6b-4,8b= -6-7,2;

-1,2b= -13,2;

b= -13,2/(-1,2)

b=11

Answer 3

To solve the equation $1.2(3b+5) = 2(2.4b-3.6)$, we'll follow these steps:

Step 1: Distribute the coefficients inside the parentheses. Step 2: Simplify the equation. Step 3: Solve for $b$.

Let's start with step 1:

$1.2(3b+5) = 2(2.4b-3.6)$

Distribute the coefficients:

$3.6b + 6 = 4.8b - 7.2$

Now, let's move on to step 2 and simplify the equation:

Subtract $3.6b$ from both sides and add $7.2$ to both sides:

$6 = 1.2b - 7.2$

Now, add $7.2$ to both sides to isolate $1.2b$:

$13.2 = 1.2b$

Finally, let's solve for $b$ in step 3:

Divide both sides by $1.2$:

$b = \frac{13.2}{1.2}$

$b = 11$
