2x + 3 = 7

418 = -22a

What are the VARIABLES in these two equations?​

x=2

a=19

Step-by-step explanation:

2x+3=7

2x+3-3=7-3

2x=4

2x/2=4/2

x=2

418=-22a

418/(-22)=-22a/(-22)

19=a

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y
