Question

Is the given number a solution of the equation?

13 – d = 8; 5

Answer 1

try to solve the eqn ...
u can find the answer

Answer 2

so you already know the answer apparently

Answer 3

then the problem is
13-d=8
and you want to know the steps?

Answer 4

13-d=8
-d=8-13
minus will get cancelled fom both the sides
d=5
yea its correct

Answer 5

or equally valid approach:
13-d=8
add d to both sides:
13=8+d
subtract 8 from both sides
5=d
and low and behold you get the same answer
