{{{p=218-5t}}}

Part b: Write an equation that represents Steven's weight. 

Let {{{p}}}= his weight and {{{t}}}= the number of weeks

{{{p=186-t}}}

Part c: After how many weeks will Elton and Steven weigh the same number of pounds.

{{{218-5t=186-t}}}

After {{{8}}} weeks will Elton and Steven weigh the same number of pounds.

check:

{{{p=218-5t=218-5*8=218-40=178}}}->Elton

{{{p=186-t=186-8=178}}}->Steven
