Question

Q.10 If ( 2+5y) =12 and y = 6 , find the value of 83+125y3​

Answer 1

Answer:26946

Step-by-step explanation:

2x+3y=12 and y=6

then we get x by substituting y in the given equation

2x+3(6)=12

2x+18=12

2x=-6

x=-3

then in question they ask 8x^3+125y^3= 2(-27)+125(216)=26946

then final answer is 26946
