Question

How do you solve the system of equations `-8x + 7y = -4` and `56x - 49y = 29`?

Answer 1

There are no solutions to this pair of equations.

Explanation:

Since `(56x-49y)` is a multiple of `(-8x+7y)` these equations represent lines with the same slope.

Since `(29)` is not that same multiple of `(-4)` the equations represent lines that are not co-linear; they are a pair of parallel lines.
graph{(-8x+7y+4)(56x-49y-29)=0 [-0.085, 0.8506, -0.4397, 0.0276]}
