Question

What is the solution to the linear equation? d – 10 – 2d + 7 = 8 + d – 10 – 3d d = –5 d = –1 d = 1 d = 5

Answer 1

Its C. d=1

Explanation:

I just took the quiz

Answer 2

-1 =d

Explanation:

d – 10 – 2d + 7 = 8 + d – 10 – 3d

Combine like terms

-3d -3 = -2d -2

Add 3d to each side

-3d -3 +3d= -2d -2+3d

-3 = d-2

Add 2 to each side

-3+2 = d-2+2

-1 =d
