Question

5х – 3|y + 2| при х = - 2, у = - 4 по действиям

Answer 1

Вот так вроде бы нам так объясняли

Answer 2

To find the value of the expression 5x - 3|y + 2| when x = -2 and y = -4, we substitute the given values of x and y into the expression and perform the necessary calculations.

Step 1: Substitute the given values of x and y into the expression: 5(-2) - 3|(-4) + 2|

Step 2: Perform the operations inside the absolute value | |: 5(-2) - 3|-4 + 2|

Step 3: Perform the multiplication and addition inside the absolute value: -10 - 3|-2|

Step 4: Calculate the absolute value |-2|: -10 - 3 * 2

Step 5: Perform the multiplication: -10 - 6

Step 6: Perform the subtraction: -16

So, when x = -2 and y = -4, the value of the expression 5x - 3|y + 2| is -16.
