Question

(14 + а ∙ 7) : 7 = 92 – 78

Answer 1

Ответ:

а=12

Пошаговое объяснение:

(14+7а):7=14

2+а=14

а=14-2

а=12

Answer 2

Let's solve the equation step by step:

(14 + а ∙ 7) / 7 = 92 - 78

First, simplify the expression within the parentheses:

(14 + а ∙ 7) = 14 + 7a

So, the equation becomes:

(14 + 7a) / 7 = 92 - 78

Now, simplify further:

(14 + 7a) / 7 = 14

Now, to isolate 'a,' multiply both sides of the equation by 7:

(14 + 7a) = 14 * 7

14 + 7a = 98

Subtract 14 from both sides to solve for 'a':

7a = 98 - 14 7a = 84

Now, divide both sides by 7 to find the value of 'a':

a = 84 / 7 a = 12

So, the solution to the equation is a = 12.
