Answer:
no solution
Explanation:
given the system of equations
2x + 3y = 12 → (1)
7 + 3y = - 2x ( add 2x to both sides )
2x + 3y + 7 = 0 ( subtract 7 from both sides )
2x + 3y = - 7 → (2)
subtract (2) from (1) term by term
(2x - 2x) + (3y - 3y) = 12 - (- 7) , that is
0 + 0 = 12 + 7 , resulting in
0 = 19 ← not possible
This situation indicates the system has no solution
