Answer:
12.16700 cm^3
Step-by-step explanation:
2.3^3 is equal to 12.16700
Using the given equations to solve:
2x + 7y = 4
-4x - 3y = 14
Expressing one equation in terms of x:
2x + 7y = 4
2x = 4 - 7y
x = (4 - 7y)/2
Substituting to the other equation:
-4 [(4 - 7y<span>)/2</span>] - 3y = 14
-8 + 14y - 3y = 14
11y = 22
y = 2
Substituting back to the first equation:
2x + 7(2) = 4
2x + 14 = 4
2x = -10
x = -5
Therefore, (x,y) = (-5 , 2)
