Question

3|1-х|-4|-у| при х=3,у=4 Как решить?

Answer 1

Ответ:

Пошаговое объяснение:

3*|1-x|-4*|-y|=3*|1-3|-4*|-4|=3*|-2|-4*|-4|=3*2-4*4=6-16=-10.

Answer 2

To solve the expression 3|1-х|-4|-у| with given values for x and y (x=3, y=4), follow these steps:

Step 1: Replace the variables with their respective values: Substitute x=3 and y=4 into the expression: 3|1-3|-4|-4|

Step 2: Simplify the absolute values first, starting from the innermost: 3|1-3| = 3|-2|

Step 3: Calculate the absolute value of -2: | -2 | = 2

Step 4: Substitute the result back into the expression: 3 * 2 - 4 - 4

Step 5: Perform the remaining arithmetic operations from left to right: 6 - 4 - 4 = 2

So, when x=3 and y=4, the value of the expression 3|1-х|-4|-у| is 2.
