Question

solve equation step by step:-
45= -7d-4​

Answer 1

Answer:

45=-7d-4

45+4=7d

49=7d

d=49/7

d=7

Answer 2

Answer:

45=-7d-4

We move all terms to the left:

45-(-7d-4)=0

We get rid of parentheses

7d+4+45=0

We add all the numbers together, and all the variables

7d+49=0

We move all terms containing d to the left, all other terms to the right

7d=-49

d=-49/7

d=-7
