Ireally need on this question me answer i will give more points and brainless

find an ordered pair x, y, that is a solution to the equation.

-x+5y=6

just do -1 + 5 x 1 = 6

Step-by-step explanation

x=-1 and y=1

Step-by-step explanation:

order pair must satisfy the equation so by putting random number which in this case is very easy we can satisfy the equation

we have to choose x and y value as such that after solving LHS of equation it gives answer as 6

so -(-1)+5(1)=6

1+5+=6

6=6

so ordered pair is (-1,1)

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

it would be 6xy and -16xy.
