Question

What is the solution to the linear equation?

Answer 1

Answer:

-10 -2d+7=8-10-3d

-2d + 7 =8 -3d

-2d + 7 =3d = 8

-2d + 3d = 8-7

d=8-7

d=1

Answer 2

Answer:

$d = 1$

Step-by-step explanation:

Step 1:  Combine like terms

$d - 10 - 2d + 7 = 8 + d - 10 - 3d$

$(d - 2d) + (-10 + 7) = (8 - 10) + (d - 3d)$

$(-d) + (-3) = (-2) + (-2d)$

Step 2:  Add 2d to both sides

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

$d - 3 = -2$

Step 3:  Add 3 to both sides

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

$d = 1$

Answer:  $d = 1$
