Hello!
4x - 9y = 20
2x - 6y = 16
You first need one of the variables have the same coefficient
We can do this by multiplying the second equation by 2
4x - 12y = 32
Subtract the equations to get rid of x
4x - 9y = 20
4x - 12y = 32
3y = -12
Divide both sides by 3
y = -4
Put y into one of the original equations
2x - 6(-4) = 16
Multiply
2x - -24 = 16
We you subtract a negative it is the same as addding
2x + 24 = 16
Subtract 24 from both sides
2x = -8
Divide both sides by 2
x = -4
The answers are x = -4 and y = -4
Hope this helps!
2.5, because 6 2/3 - 4 1/6....
First, find the most common denominator! Which is 6.
Multiply the bottom term to 2 times. (To get 6.) Now do the same for the top! So 6 4/6 - 4 1/6
Second, you subtract!
2 3/6
Third, if your teacher has ever taught you this or not....
If she did: Simply 2 3/6 into 2 1/2!
Finally,
2 1/2 can be 2.5, 2 3/6, or just 2 1/2!

The answer to your question is b 3 to the 6power. The reason why is there are 6 3 so instead writing 3*3*3*3*3*3 you can just do 3 to the 6 power.
Hope this helps:)
