Solve the following system of equations using substitution. What is the value of y? 2x + 3y = 105 x + 2y = 65
15
25
40
65
To solve the system of equations using substitution, we'll solve one equation for x and substitute it into the other equation.
We can solve the second equation for x as follows:
x + 2y = 65
x = 65 - 2y
Now, substitute this value of x into the first equation:
2x + 3y = 105
2(65 - 2y) + 3y = 105
130 - 4y + 3y = 105
-y = -25
y = 25
Therefore, the value of y is 25.
