Determine the best method to solve the system of equations. Then solve the system. x - 3y = 25 and 2x + y = 64. can you please help

(31, 2); Substitution.

Step-by-step explanation:

x - 3y = 25

Use SUBSTITUTION by setting everything in the above equation equal to x...

x = 3y + 25

2(3y +25) + y = 64

6y + 50 + y = 64

7y + 50 (-50) = 64 (-50)

7y = 14

y = 2

Then, substitute y = 2 into the original equation.

x - 3(2) = 25

x - 6 = 25

x = 31

(x, y) = (31, 2)
