Question

The following system of equation is given: -7x+7y=7\newline 2x-2y=-18−7x+7y=7

Answer 1

The given system of equation has no solution.

What is a System of Equation ?

The set of equation that have common solution is called the system of equation

The equation given are

- 7x + 7y = 7

2x - 2y = -18

On simplifying the equations

- x + y = 1

x - y = -9

On adding these equations there is no solution

as

$\rm \dfrac {a_1}{a_2 } = \dfrac{b_1} {b_2} \ne \dfrac{c_1}{c_2}$

The given system of equation has no solution.
