Mathematics for IGCSE & O level - Equations (Section 7 - No. 24)
If two quantities, A and B, are equal, and two other quantities, C and D, are equal, what does it imply about A + C and B + D?
A + C > B + D
A + C = B + D
A + C < B + D
Cannot be determined
ব্যাখ্যা
If A = B and C = D, then adding the equations leads to A + C = B + D.
