Which ordered pair (a,b) is a solution to the given system of linear equations.

egoroff_w [7]

Answer:

A. (-13,-3)

Step-by-step explanation:

Solve the system of two equations:

$\left\{\begin{array}{l}-2a+3b=14\\a-4b=3\end{array}\right.$

From the second equation:

$a=3+4b$

Substitute it into the first equation:

$-2(3+4b)+3b=14\\ \\-6-8b+3b=14\\ \\-8b+3b=14+6\\ \\-5b=20\\ \\5b=-20\\ \\b=-4$

So,

$a=3+4b=3+4\cdot (-4)=3-16=-13$

The solution is (-13,-4)
