Question

(Y:8+18)•9=540 реши уравнение и сделай проверку с комментированием

Answer 1

Y:8+18=540:9

Y:8+18=60

Y:8=60-18

Y:8=42

Y=42*8

Y=336

(336:8+18)*9=540

540=540

Answer 2

(у:8+18)*9=540

Представим (у:8+18) как первый множитель а 9 как второй множитель

у:8+18=540:9=60

Представим у:8 как первое слагаемое а 18 как второе слагаемое

у:8=60-18=42

у:8=42*8=336

Answer 3

To solve the equation (Y + 18) • 9 = 540, follow these steps:

Step 1: Simplify the equation. Step 2: Solve for Y. Step 3: Perform a check to verify the solution.

Step 1: Simplify the equation.

(Y + 18) • 9 = 540

Step 2: Solve for Y.

First, distribute the 9 to the terms inside the parentheses:

9Y + 9 * 18 = 540

Now, simplify the equation further:

9Y + 162 = 540

Next, isolate the term with Y by subtracting 162 from both sides:

9Y = 540 - 162

9Y = 378

Finally, divide both sides by 9 to find the value of Y:

Y = 378 / 9

Y = 42

Step 3: Perform a check to verify the solution.

To check if Y = 42 is the correct solution, substitute this value back into the original equation and see if both sides are equal:

(42 + 18) • 9 = 540

(60) • 9 = 540

540 = 540

Since both sides are equal, the solution Y = 42 is correct.

Commentary: The equation (Y + 18) • 9 = 540 is a simple linear equation with one variable, Y. To solve it, we followed standard algebraic steps to isolate Y on one side of the equation. After finding Y = 42 as the solution, we verified it by substituting it back into the original equation. The equation holds true, confirming that the solution is correct.
