Answer:
Let x = number of white marbles and y = number of yellow marbles.
x + y = 57 => x = 57 - y
Also, x = 3 + 5y
Substitute x for y.
57 - y = 3 + 5y => 57 - 3 = 54 = 6y
So, y = 9
Since x (our answer) = 3 + 5 (9),
x = 48.
Check: 48 + 9 = 57 total

Answer:
The answer to your question is below
Step-by-step explanation:
Inequality 1
7(x + 2) - 8 ≥ 13
7x + 14 - 8 ≥ 13
7x + 6 ≥ 13
7x ≥ 13 - 6
7x ≥ 7
x ≥ 7/7
x ≥ 1
Inequality 2
8x - 3 < 4x - 3
8x - 4x < - 3 + 3
4x < 0
x < 0 / 4
x < 0
