Step-by-step explanation:
not really sure hope you get this right im sooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo sorrryyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy i9f you get this wrong
2+4z-18
change it so it's an equation
2+4z-18=0
then get 4z alone on one side by subtracting 4z from both sides
2-18=-4z
-16= -4z
divide both sides by -4
a negative divided by a negative becomes positive
4 =z
plug it in
2+4(4)-18
4x4 is 16
2+16-18=0
0=0
the same can be done for the second one 2+k-8
make it 2+k-8=0
move the k to get it alone so subtract k from both sides
2-8=-1k
-6 = -1K
you can divide by K to make K=6
plug in 2+6-8=0
0=0
Multiply the denominator by the whole number, then add the numerator. That's your top number...numerator stays the same. Easiest way I learned it.
2 4/5 = 5*2=10+4=14
Answer= 14/5 (Example)
The first graph is the answer
