Step-by-step explanation:

you would multiply d1 and d2 by 1/2, then add negative d2/2 to each side, then divide each side by 2/1.

hope it helps

Answer:

[tex]d=\frac{2M}{3}[/tex]

Step-by-step explanation:

Switch sides

[tex]\frac{1}{2}\left(d\cdot \:1+d\cdot \:2\right)=M[/tex]

Multiply both sides by 2 to remove the fraction

[tex]2\cdot \frac{1}{2}\left(d\cdot \:1+d\cdot \:2\right)=2M[/tex]

Then simplify

[tex]3d=2M[/tex]

  • Divide both sides by 3

[tex]\frac{3d}{3}=\frac{2M}{3}[/tex]

[tex]d=\frac{2M}{3}[/tex]
