Question

7х-6у при х=-5/7; у=1/3

Answer 1

Ответ:

-7

Пошаговое объяснение:

$7*(-\frac{5}{7} ) -6*\frac{1}{3}$ = -5-2= -7

Answer 2

To evaluate the expression 7x - 6y when x = -5/7 and y = 1/3, we can substitute these values into the expression and perform the calculation.

Let's substitute the values: x = -5/7 y = 1/3

7x - 6y = 7(-5/7) - 6(1/3)

Now we simplify the expression:

7(-5/7) = -5 (the 7s cancel out) -6(1/3) = -2 (multiply -6 by 1/3)

Therefore,

7x - 6y = -5 - 2 = -7

So when x = -5/7 and y = 1/3, the value of 7x - 6y is -7.
