Solve the given system, using the substitution method.

y = 4x – 6
8x – 2y = 14

(Points : 1)
       (14, 12)
       (12, 14)
       There are an infinite number of solutions.
       There is no solution.

anonymous · Answer

substitute the numbers 14->x,12->y

Solve, using the substitution method.

2x + 3y = 1
y = x – 8

(Points : 1)
       (0, –8)
       (2, –6)
       (4, –4)
       (5, –3)
