D. Write an original equation and solve.
Eight fewer than twice the sum of x and 4 is 10.

Answer:
2(x+4) - 8 = 10
Step-by-step explanation:
the sum of x and 4: x+4
twice the sum of x and 4: 2(x+4)
eight fewer than twice the sum of x and 4: 2(x+4) - 8
eight fewer than twice the sum of x and 4 is 10: 2(x+4) - 8 = 10
