-4y+5x=8
3y-3x=-3 --> divide by (3) y-x=-1
then multiply by (4) 4y-4x=-4
-4y+5x=8
4y-4x=-4
---------------
x=4
then plug x=4 in
4y-4x=-4
4y-4(4)=-4
4y-16=-4
4y=12
y=3
solution: (4;3)
The answer is b because 7 times 7 is 49
Answer:
M is 1.5
Step-by-step explanation:
Use M = 1/O
Replace 1 with a letter such as K
So you use M = K/O
Substitute values
0.5 = K/6
To get K times 0.5 by 6
You get 3
So K=3
Use the equation from the start to find M
M=3/2
M IS 1.5
