You are given 3x +2x =16 and 2x + y =9. You are asked to find the x and
y values. This is a substitution method. We need to denote 3x +2x =16 as the first equation and 2x + y = 9 as the
second equation. First, we convert the first equation into x terms.



3x +2x =16


5x
= 16

X
= 16/5



Substitute the value of x to the second equation,


2x + y = 9


2(16/5) + y = 9

Y = 13/5
