The given system of equations has only one solution
The solution is (x, y) = (-1, 0)
<u>Solution:</u>
<em><u>Given system of equations are:</u></em>
-7x - 2y = 7 ---- eqn 1
4x + 6y = -4 --- eqn 2
We have to find solution for this system of equations by substitution method
From eqn 2,
4x + 6y = -4
2x + 3y = -2
2x = -2 - 3y
--- eqn 3
Substitute eqn 3 in eqn 1
Substitute y = 0 in eqn 1
-7x -2(0) = 7
-7x = 7
<h3>x = -1</h3>Thus the solution is (x, y) = (-1, 0)
Therefore the given system of equations has only one solution
