Question

The system of equations 4x -3y +12 =0 and 2x +3y -15 =0 has

• A. a unique solution
• B. infinitely many solutions
• C. no solution
• D. 2 solutions

Answer 1

The correct option is A

a unique solution

$\frac{a_1}{a_2}$ ≠ $\frac{b_1}{b_2}$ ≠ $\frac{c_1}{c_2}$

Therefore, the following system of equations has a unique solution.
