For u math people out there - 7+3d-5=-1+2d-12+d and I would very much like it if u would show how to do it

So do the like terms first

lets start with the left side

7-5 = 2

so itd turn into 2+3d = 1+2d-12+d

now combine like terms on the right side

2+3d = - 11 + d

now subtract d from both sides

2+2d=11

now subtract 2 from both sides

2d=9

now divide 2 by 9

d = 4.5

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

Collect like terms on the right side of the equation:

-1 and - 12 make - 13

2d and 1d make 3d

Do the same on the left side:

7 and - 5 make 2

So now the equation looks like this:

3d+2=3d-13

Bring 3d to the other side by subtracting it from both sides (doing the opposite)

(3d+2) - 3d=-13 (3d cancels itself out)

3d+2-3d=-13

Collect like terms:

3d and - 3d make a 0 pair

Equation now looks like this:

2=-13

Finish by subtracting 2 from both sides:

2-2=-13-2

0=-15
