Answer 1

Step-by-step explanation:

for 1st condition satisfies the equation for Option (1)

the given equation is 2×3+6-12÷4=17

as replacing × and +

2+3×6-12÷4=17

2+18-3=17

20-3=17

17=17

for 2nd condition satisfies the equation for Option (2)

the given equation is 12÷2-6×3+8=16

as replacing - and +

12÷2+6×3-8=16

6+18-8=16

24-8=16

16=16
