Question

0=(а+1)-3+а-1 Найдите значение а

Answer 1

Здравствуйте!

$(a + 1) - 3 + a - 1 = 0 \\ (a + 1) - 4 + a = 0 \\ a + 1 - 4 + a = 0 \\ a - 3 + a = 0 \\ 2a - 4 = 0 \\ 2a = 4 \\ a = 4 \div 2 \\ a = 2$

Ответ: 2.

Удачи в учебе!

Answer 2

To solve the equation and find the value of а, let's simplify and solve the equation step by step:

0 = (а + 1) - 3 + а - 1

Step 1: Combine like terms: 0 = 2а - 3

Step 2: Add 3 to both sides to isolate 2а on one side of the equation: 3 = 2а

Step 3: Divide both sides by 2 to solve for а: а = 3 / 2

So, the value of а is 3/2 or 1.5.
