Question

3⋅(6a−5)−6⋅(13a+5)=−95.

Answer 1

Ответ:

a=5/6

Пошаговое объяснение:

3(6a-5)-6(13a+5)=-95

18a-15-78a-30=-95

18a-78a=-95+15+30

-60a=-50

a=5/6

Answer 2

18а-15-78а-30=-95

-78a+18a=-95+15+30

-60a=140 /÷2

-30a=70 /÷10

-3a=7

a=7/3

Answer 3

To solve the equation 3(6a - 5) - 6(13a + 5) = -95, follow these steps:

Step 1: Distribute the constants inside the parentheses. 3 * 6a - 3 * 5 - 6 * 13a - 6 * 5 = -95 18a - 15 - 78a - 30 = -95

Step 2: Combine like terms. (18a - 78a) + (-15 - 30) = -95 -60a - 45 = -95

Step 3: Add 45 to both sides to isolate the variable term. -60a = -50

Step 4: Divide both sides by -60 to solve for 'a'. a = (-50) / (-60) a = 5/6

So, the solution to the equation is a = 5/6.
