Question

9 = d + 12 solve in inverse operation​

Answer 1

Question -:

9 = d + 12. Solve in inverse operation.

$\huge\bold{\mathfrak{\purple{A{\pink {n {\green {s{\blue{w{\red{e {\orange {r}}}}}}}}}}}}}$

9 = d + 12

d + 12 = 9

d = 9 - 12

d = - 3.

Verification -:

Putting -3 in place of x, we get -:

9 = -3 + 12

9 = 9.

Since x = -3 satisifes the equation,

Hence verified.

Hope it helps! :)

Answer 2

Step-by-step explanation:

9=d+12

d+12=9

d=9-12

d=-3

putting 3 in place of x,

9=-3+12

9=9
