Question

your lunch and your friend steve's lunch cost 19.00. Your lunch was 3.00 more than steve's lunch. How much was steve's lunch?

Answer 1

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 2

Answer:

$8.00

Step-by-step explanation:

y + s = 19; y = 3 + s

3 + s + s = 19

2s = 16

s = 8
