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
