Answer:
Step-by-step explanation: Given a number N. Given two numbers X and Y, the task is to find the sum of all those numbers from 1 to N that are divisible by X or by ... Sn = (n/2) * {2*a + (n-1)* d} ... + (N / (X * Y) - 1) * (X * Y))/ 2;. return S1 + S2 - S3;. } // Driver code. int main().
hope this is right
8x+16=8x-16 is no solution because it is 32=0
-3x-17=-(17+3x) is infinitely many solutions because it is 0=0
9x+27=27 is one solution because it is x=0
2x-6=6+2x is no solution -12=0
what's the question? you only put a formula
#5= 37.5:62.5 i think its good
