Answer 3

When x = 2 and y = 4×+6-y,

y = 4(2) + 6 - y
y = 8 + 6 - y
2y = 14

Therefore, y = 7.

Now, we can substitute y = 7 into the original expression:

x + y
= 2 + 7
= 9

Therefore, the evaluated expression is:

9

Answer 4

Apologies for the confusion. Let's re-evaluate the expression.

Given:
x = 2
y = 4x + 6 - y

Substituting the value of x into the expression for y:
y = 4(2) + 6 - y
y = 8 + 6 - y
2y = 14
y = 7

Now we substitute the values of x = 2 and y = 7 into the expression:

Expression = *

= 2 + 7
= 9

Therefore, the value of the expression when x = 2 and y = 4x + 6 - y is 9.

Answer 5

To evaluate the expression 5c - 2k when c = 6 and k = 2, we substitute the given values into the expression:

5c - 2k = 5(6) - 2(2)
= 30 - 4
= 26

Therefore, the value of the expression 5c - 2k when c = 6 and k = 2 is 26.
