Question

80-a=60:3 решить уровнение

Answer 1

Ответ: 60

Пошаговое объяснение: 60:3=20

80-а=20

а=80-20

а=60

Answer 2

To solve the equation 80 - a = 60 ÷ 3, we'll follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction).

First, let's simplify the right side of the equation: 60 ÷ 3 = 20

The equation becomes: 80 - a = 20

To isolate the variable 'a,' we can subtract 80 from both sides of the equation: 80 - a - 80 = 20 - 80

This simplifies to: -a = -60

To solve for 'a,' we can multiply both sides of the equation by -1 to eliminate the negative sign: -1 * -a = -1 * -60

This gives us: a = 60

Therefore, the solution to the equation 80 - a = 60 ÷ 3 is a = 60.
