Question
Verify:
{7 − (−7)} × 7 = 7 × 7 − (−7) × 7
Advertisements
Solution
{7 − (−7)} × 7 = 7 × 7 − (−7) × 7
Step 1: Simplify the left-hand side (LHS)
LHS = {7 − (−7)} × 7
Simplify 7 − (−7)
7 − (−7) = 7 + 7 = 14
LHS = 14 × 7 = 98
Step 2: Simplify the right-hand side (RHS)
RHS = 7 × 7 − (−7) × 7
Simplify each term
7 × 7 = 49, (−7) × 7 = −49
RHS = 49 − (−49) = 49 + 49 = 98
Step 3: Compare LHS and RHS
LHS = 98, RHS = 98
Since both sides are equal, the equation is verified.
{7 − (−7)} × 7 = 7 × 7 − (−7) × 7
