Question

3(4d-2)+8+2(d+5)=2d-1+d+7+10(2-d)

Answer 1

3(4d-2)+8+2(d+5)=2d-1+d+7+10(2-d)
12d-6+8+2d+10=2d - 1 + d +7+20 - 10d
12d+2d-2d-d+10d= -1+7+20+6-8-10
21d=14
d=$\frac{14}{21}$simplificamos
d=$\frac{2}{3}$

Espero que sirva! Saludos!

Answer 2

3(4d-2)+8+2(d+5)=2d-1+d+7+10(2-d)
12d-6+8+2d+10=2d - 1 + d +7+20 - 10d
12d+2d-2d-d+10d= -1+7+20+6-8-10
21d=14
d=simplificamos
d=
