The solution of the given equtions are x = 6 and y = -5.
There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
In another word, the equation must be constrained with some constraint.
Given that
4x - 5y = 49 and 2x + 7y = -23
Multiplying by 2 of the second equation.
4x + 14y = -46
Now subtracting two - one
y = -5 and by that x = 6
Hence the correct answer to the given equation will be -5 and 6.
