Question

(50-а) - 4 = (50-30) - 4 = 16

Answer 1

А=30..................

Answer 2

Let's simplify the equation step by step:

1. Start with the left side of the equation: (50 - a) - 4

2. Subtract 4 from the result of (50 - a): (50 - a) - 4 = 50 - a - 4

3. Now, let's simplify the right side of the equation: (50 - 30) - 4 = 20 - 4 = 16

So, you correctly simplified the right side of the equation to 16.

Now, let's simplify the left side further: 50 - a - 4

To simplify this, subtract 4 from 50: 50 - 4 = 46

So, the left side simplifies to 46 - a.

Now, we have:

Left side: 46 - a Right side: 16

So, the equation is: 46 - a = 16

To solve for 'a,' you can isolate 'a' on one side of the equation:

Subtract 16 from both sides of the equation:

46 - a - 16 = 16 - 16

This simplifies to:

30 - a = 0

Now, add 'a' to both sides to isolate 'a':

30 - a + a = 0 + a

This simplifies to:

30 = a

So, the value of 'a' is 30.
