Answer 2

Answer:

1. & 2. are correct equations

Step-by-step explanation:

1) 4 + 8 - 12 = 16

Change "4" into "8" & "8" into "4". Similarly, "+" into "-" and "-" into "+".

→ 8 - 4 + 12 = 16

→ 4 + 12 = 16

→ 16 = 16

2) 4 - 8 + 12 = 0

Change "4" into "8" & "8" into "4". Similarly, "+" into "-" and "-" into "+".

→ 8 + 4 - 12 = 0

→ 12 - 12 = 0

→ 0 = 0

3) 8 + 4 - 12 = 24

Change "4" into "8" & "8" into "4". Similarly, "+" into "-" and "-" into "+".

→ 4 - 8 + 12 = 24

→ - 4 + 12 = 24

→ 8 = 24

4) 8 - 4 + 12 = 8

Change "4" into "8" & "8" into "4". Similarly, "+" into "-" and "-" into "+".

→ 4 + 8 - 12 = 8

→ 12 - 12 = 8

→ 0 = 8

From above we can say that both 1) and 2) are correct. As L.H.S. = R.H.S. in them.
