How do you complete each ordered pair (3, _) so that it is a solution to 6x - y = 7?

Answer 1

Eva Abramson

See the entire solution process below:

y = 7#- #(6 xx color(red)(3))

y = 7# - #18

18 - y + #color(red)(-18) = 7 color(red)(- 18)#

#0 - y = -11#

#-y equals -11#

xx -y = color(red)(-1) xx -11#

#y equals 11#

The pair in order is #(3, 11)#.

To complete the ordered pair (3, _) so that it is a solution to 6x - y = 7, substitute x = 3 into the equation and solve for y:

6(3) - y = 7 18 - y = 7 -y = 7 - 18 -y = -11 y = 11

So, the completed ordered pair is (3, 11).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
