Answer 2

having trouble with it

Answer 3

solve for d do you konw how

Answer 4

tried solving but I don't think I did it right

Answer 5

can you show us??

Answer 6

yeah

Answer 7

2+3d=-13+3d
+2 +2 3d=-11+3d d=this is where I get lost

Answer 8

2 + 3d = -13 + 3d
subtract 3d from both sides
2 + 3d - 3d = -13 + 3d - 3d
combine like terms
2 = -13 (incorrect)

There is no solution to this problem

Answer 9

Solution for 7+3d-5=-1+2d-12+d equation:

Simplifying
7 + 3d + -5 = -1 + 2d + -12 + d

Reorder the terms:
7 + -5 + 3d = -1 + 2d + -12 + d

Combine like terms: 7 + -5 = 2
2 + 3d = -1 + 2d + -12 + d

Reorder the terms:
2 + 3d = -1 + -12 + 2d + d

Combine like terms: -1 + -12 = -13
2 + 3d = -13 + 2d + d

Combine like terms: 2d + d = 3d
2 + 3d = -13 + 3d

Add '-3d' to each side of the equation.
2 + 3d + -3d = -13 + 3d + -3d

Combine like terms: 3d + -3d = 0
2 + 0 = -13 + 3d + -3d
2 = -13 + 3d + -3d

Combine like terms: 3d + -3d = 0
2 = -13 + 0
2 = -13

This equation is invalid, the left and right sides are not equal, therefore there is no solution
