You have the correct answer on your paper so you should be good if not let me know what else you need:)
X = 6y - 3
x + y = 53
6y - 3 + y = 53
7y - 3 = 53
7y = 53 + 3
7y = 56
y = 56/7
y = 8
x = 6y - 3
x = 6(8) - 3
x = 48 - 3
x = 45
ur numbers are : 8 and 45
I'm not sure but I think its c
it’s system of substitutions ?
so try
a = 2
b = 5
1 liter = 1,000 ML
2 X 1,000 = 2,000 ML
2,000 milliliter is your answer
