Step-by-step explanation:
Okay this is basically polynomial algebra:
1. Add the value of the lengths already given.
like terms: 3x + x = 4x, -4 + 2 = -2. Now you're left with, 4x - 2.
2. Find the difference between the perimeter and the sum of the lengths.
(10x -3) + (4x + 2) = 6x - 1

Answer:
40 grams
Step-by-step explanation:
y * 25% + x * 10% = 120 * 15%
x = 120 - y
(120-y) * 10% = x * 10%
y * 25% + (120 - y ) * 10% = 120 * 15%
0.25y + 12 - 0.1y = 18
0.15y = 6
y = 6 / 0.15
y = 40
