Question

Y-(52-13)=17, 28+34+a=100​

Answer 1

У-(52-13)=17
у-39=17
у=17+39
у=56
проверяем:
56-(52-13)=17
56-39=17
17=17

28+34+а=100
62+а=100
а=100-62
а=38
проверяем:
28+34+38=100
62+38=100
100=100

Answer 2

У-(52-13)=17
у-39=17
у=17+39
у=56
56-(52-13)=17

Answer 3

To solve the given equations, we need to find the values of the variables "Y" and "a."

1. Y - (52 - 13) = 17

Let's solve this step by step:

Step 1: Simplify the expression inside the parentheses: 52 - 13 = 39

Step 2: Substitute the value into the equation: Y - 39 = 17

Step 3: Isolate the variable "Y" on one side of the equation by adding 39 to both sides: Y = 17 + 39

Step 4: Perform the addition: Y = 56

So, the value of "Y" is 56.

2. 28 + 34 + a = 100

Let's solve this equation:

Step 1: Perform the addition on the left side of the equation: 28 + 34 + a = 62 + a

Step 2: Isolate the variable "a" on one side of the equation by subtracting 62 from both sides: a = 100 - 62

Step 3: Perform the subtraction: a = 38

So, the value of "a" is 38.

Final solutions: Y = 56 a = 38
