Answer:
(-1,1)
Step-by-step explanation:
x + 9y = 8
-6x - 9y = -3
Add the two equations together to eliminate y
---------------------
-5x = 5
Divide by -5
-5x/-5 = 5/-5
x = -1
Now solve for y by substituting into the first equation
x+9y = 8
-1 + 9y =8
Add 1 to each side
-1+1 + 9y = 8+1
9y=9
Divide each side by 9
9y/9 = 9/9
y = 1

CCC 7(15)+6 105+6=111
SC 6(15)-3 90-3 = 87
111-87 = 24
336
10 times 280 over 100 equals 28 time 12 equals 336
8.6*9.2=79.12
Hope this helps!
