Three more than twice the sum of a number and half the number equals 105. which equation models this relationship?
a 2(x+1/2x)+3=105
b 2x+1/2x+3=105
c 2x+3=1/2x+105
d 2(x+3)=1/2x+105

it's a.

three more is +3 and it equals 105

that already eliminates c and d

next it says twice the sum of a number and half the number
