7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84.
The first 10 multiples of 7 are: 7, 14, 21, 28, 35, 42, 49, 56, 63, and 70.
replace 7 with x: x+2x=3x x+2x+3x=6x all ten of them -> 55x Put the 7 back in: 55(7)=385 OR: The first ten multiples of 7 are 7,14,21,28,35,42,49,56,63,70 The product of the multiples will then be 7+14+21+28+35+42+49+56+63+70= 385 :)
