Answer:
1. D × 9 - D ÷ D + 7
→ Change every D into 3 in the equation.
3 × 9 - 3 ÷ 3 + 7
→ Solve the equation from left to right. Do NOT forget to follow the PEMDAS Rule.
= 27 - 3 ÷ 3 + 7
= 27 - 1 + 7
= 26 + 7
= 33
2. 96 ÷ T × 6 - T + 9
→ Change every T into 4 in the equation
96 ÷ 4 × 6 - 4 + 9
→ Solve the equation from left to right. Do NOT forget to follow the PEMDAS Rule.
= 24 × 6 - 4 + 9
= 144 - 4 + 9
= 140 + 9
= 149
