Let

x--------> the number of weeks

y--------> Jon weighs in lb

z--------> Matt weighs in lb

we know that

y = 148+2x ----> equation

z = 198-x ----> equation

equate equation and equation

148+2x=198-x

2x+x=198-148

3x=50

$x=\frac{50}{3} =16.7\ weeks$

using a graph tool

see the attached figure

therefore

the answer is

On the th week
