Question

12963 : у = 321 + 40 × 100

Answer 1

12963/y=321+40*100

12963=y*4000+321y

(с y в одну сторону, без у другую) y*4000+321y=12963

4000y+321y=12963

4321y=12963

y=3

Ответ : y=3

Answer 2

12963:у=321+40•100

12963:у=321+4000

12963:у=4321

у=12963:4321

у=3

12963:3=321+40•100

100=100

Answer 3

To solve the expression 12963: у = 321 + 40 × 100, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right).

In this expression, you have multiplication and addition. So, first, you should perform the multiplication, and then the addition:

1. 40 × 100 = 4000
2. Then, add 321 to 4000: 321 + 4000 = 4321

So, the value of у is 4321.
