Answer:
x=-2
y=5
Step-by-step explanation:
x=28-6y
2x-3y=-19
(substitute the value of x)
2(28-6y)-3y=-19
y=5
x=28-6*5
x=-2
411 is the total amount of shells he would use
Perimeter is all outside lengths added up. So 8+8=16. 15+15=30
16+30= 46.
First you right the problem out:
x - 6 = 20 - 19
x - 6 = 1
x = 6 + 1
x = 7
Answer: 7
