(109+695)-4=800.
2способ))
800-(109-4)=695

Answer 2

Ответ:

Пошаговое объяснение:

1-й сопсоб:

(109 +y) - 4= 800

у+105=800

у=695

2-ой способ:

(109 +y) - 4= 800

109+у=804

у=804-109

у=695

Answer 3

Solving the Equation: (109 + y) - 4 = 800

To solve the equation (109 + y) - 4 = 800, we can use two different methods: algebraic manipulation and inverse operations. Let's go through both methods step by step.

Method 1: Algebraic Manipulation

Step 1: Remove the parentheses by distributing the positive sign to both terms inside the parentheses: (109 + y) - 4 = 800 109 + y - 4 = 800

Step 2: Combine like terms: 109 - 4 + y = 800 105 + y = 800

Step 3: Isolate the variable y by subtracting 105 from both sides of the equation: 105 + y - 105 = 800 - 105 y = 695

Therefore, the solution to the equation (109 + y) - 4 = 800 is y = 695.

Method 2: Inverse Operations

Step 1: Start with the equation: (109 + y) - 4 = 800

Step 2: Undo the subtraction by adding 4 to both sides of the equation: (109 + y) - 4 + 4 = 800 + 4 109 + y = 804

Step 3: Undo the addition by subtracting 109 from both sides of the equation: 109 + y - 109 = 804 - 109 y = 695

Again, the solution to the equation (109 + y) - 4 = 800 is y = 695.

Note: Both methods yield the same solution, which is y = 695.
