Which rule gives the same relationship between x and y as x + y = 6?
a. y = x + 6

c. y = 6 - x

b. y = x - 6

d. y = -6 - x

x + y = 6

relationship: x = 6 -y or y = 6-x

so c. y = 6 - x

show work:

x + y = 6

subtract x to both sides

x + y -x = 6 -x

simplify

y = 6-x

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.
