Question

-4d + 2(3 + d) = -14 Please help

Answer 1

-4d + 2(3+d)= -14
distribute the 2(3+d)
-4d + 6+ 2d= -14
Combine the like terms
-4d + 2d + 6= -14
-2d + 6 = -14
subtract 6 to -14 
-2d = -20
divide by -2
d= -20/-2
d= 10
Check your answer 
-4(10) + 2(3+ 10) = -14
-40 + 6 + 20
-40 + 26= -14

Answer 2

It is -20 divides by -2
