Kayla
Tom is 4U
Jerry is 1U
Ali is 4U+36

279-36=243
243/9=27

27*4=108 (tom)
108-27=81

Kayla, in your solution you defined variables but then never used them

Jerry's marbles --- x
Tom's marbles ---- 4x
Ali's marbles ---- 4x + 36

their sum is 279

x + 4x + 4x+36 = 279
9x = 243
x = 27

Jerry has 27 marbles
Tom has 108 marbles
Ali has 144 marbles

Tom has 81 more marbles than Jerry
