You and two friends scored all 7 runs for your team in a baseball game. Jeff scored twice as many runs as you, and Mary scored twice as many runs as Jeff. How many runs did Jeff score?

runs scored by you  x
runs scored by Jeff  2x
runs scored by Mary  2(2x) = 4x
x+2x+4x=7
7x=7
x=1
Jeff scored 2(1) or 2 runs , (you had one and Mary had 4)
