Answer:
Steve's lunch is $8.00
Step-by-step explanation:
First you have to make a formula for this almost.
s= Steve's lunch
y= your lunch
s= y-3
s+y-19
then plug in s
y-3+y=19
Then simplify 2y-3=19
Add the three to both sides 2y=22
Divide both sides by 2 y=11
Last plug y into one of your formulas
s=Y-3
s=11-3
s=8
BE SURE TO CHECK YOUR ANSWER S+Y=19 11+8=19 :)
Answer:
$8.00
Step-by-step explanation:
y + s = 19; y = 3 + s
3 + s + s = 19
2s = 16
s = 8
