2x - 3y = 7 and -3x + y = 7..multiply Equation 2 by THREE and add to Equation 1
-9x + 3y = 21...........................watch the y's disappear
-7x........ = 28
x = -4
substitute -4 instead of x in either of the ORIGINAL equations
2x - 3y = 7
2(-4) - 3y = 7
-8 -3y = 7..........add 8 to both sides
-3y = 15
y = -5
im not sure
3 + 3 + 1 = 7
3 + 3 are the double ones
+1
=7
Complete the equation of variation where y varies inversely as x and y = 0.125
when x=8
What is the answer to this wrok
