Use Subtraction
1. Subtract
x+2y=7
3x-2y=-3
-------------
4x+0y=4 SIMPLIFY 4x=4
2. DIVIDE
4x=4
x=1
Substitute that into either of the original equations to get x=1, y=3
Answer:
120 is the y intercept in the formula y=mx+b
hope this helped!!
Answer:
17
Step-by-step explanation:
The discount on the shirt is 15%
Discount = price* discount rate

The new price is the previous price minus the discount
new price = 20-3
new price = 17
Probability=blue marbles/total marbles
