3 to the 4th power = 3x3x3x3 which is 81 :)
Answer:
4 times 3 similar is 9 it could be something times 9 for the second.
Answer:
x=1 y=1
Step-by-step explanation:
Let's use the elimination method.
3x+4y=7
2x-y = 1 (multiply both sides by 4)
8x-4y=4
3x+4y=7
(add both equations together)
11x=11
x=1
Plug x=1 into either of the equations
2(1) - y=1
2-y=1
2=1+y
y=1
Y=-6-x is not equal to 2x+y=12. Both sides were not divided by two when it was simplified.
