MARK AS BRAINLIEST ANSWER

Step-by-step explanation:

13×6= 5+9+A+8+17+21

78=60+A

A=78-60

A=18

Answer 2

13 × 6 = 5 + 9 + a + 8 + 17 + 21

Multiply and add the like terms

∴ 78 = 60 + a

Move terms

∴ -a = 60 - 78

Calculate

∴ -a = -18

Both the minus signs gets cancelled

∴ a = 18✔✔


∴ The value of a is $\boxed{\boxed{\textsf{18}}}$


Let's check the solution :-

13 × 6 = 5 + 9 + a + 8 + 17 + 21

By putting the value of 'a' as 18

∴ 78 = 60 + 18

∴ 78 = 78

∴ LHS = RHS✔
