Question

Linear equations d-7=8

Answer 1

Answer:

$\boxed{ \boxed{ \bold{ \sf{d = 15}}}}$

Step-by-step explanation:

$\sf{d - 7 = 8}$

Move constant to right hand side and change it's sign

⇒$\sf{d = 8 + 7}$

Add the numbers

⇒$\sf{d = 15}$

Let's check:

When d = 15 , R.H.S = 15 - 7 = 8

And L.H.S = 8

Thus , R.H.S = L.H.S when d = 15.

Therefore d = 15 is the solution of the equation.
