Question

7,4x-2,7y+6,3y-9,6x при х= -5 у=2

Answer 1

7,4х-2,7у+6,3у-9,6х=-2,2х+3,6ух=-5, у=2, то -2,2х+3,6у=-2,2*(-5)+3,6*2=11+7,2=18,2  

Answer 2

To evaluate the expression 7.4x - 2.7y + 6.3y - 9.6x when x = -5 and y = 2, substitute the given values into the expression:

7.4(-5) - 2.7(2) + 6.3(2) - 9.6(-5)

Now, perform the calculations step by step:

= -37 - 5.4 + 12.6 + 48

= -37 - 5.4 + 12.6 + 48

= 0.2

So, when x = -5 and y = 2, the expression 7.4x - 2.7y + 6.3y - 9.6x evaluates to 0.2.
