Answer:
nah frl
Step-by-step explanation:
I should be any more points for this but 26 per cubic meter he only has 1500 but that’ an answer of 14,000 600 m³
The sum of the left side of these two equations is equal to the same of the right side is these two equations
4x+8y + (-4x+2y) = 20 + 30
10y =50 ( x is eliminated)
y=5
Take this into the second equation
-4x +2y = 30
-4x + 2*5 = 30
x=-5
So x=-5
y=5
Solving equations simple
9n + 12 = 30
