What is the solution to this system of equations? x + y = 6
{ x = y +2
0 (3, 3)
o (4, 2)
O (2, 4)
O (6, 4

One expression below in undefined, and the other expression has a well defined value. which expression is undefined and explain why it has no value. which expression is defined? what is the value of that expression and how do you know? what is a different expression using a trig inverse function that is also undefined?

0if x and y vary inversely and y=6 as x=7, what is the constant of variation?

50 will mark show all use the linear combination method to solve the system of equations. explain each step of your solution. if steps are not explained, you will not receive credit for that step. 2x+9y= -26 -3x-7y=13
