Solve using substitution method and show all work <br><br>4x -2y = 18<br><br>-4x + 2y = -18
Travka [436]

Solving the simultaneous equation show that the solution is inconsistent.

<h3>What is Inconsistent solution?</h3>

A simultaneous equation is said to have inconsistent solution when there is no value as the solution. This implies that no value of unknown will satisfy the equation.

Hence no value of x and y satisfies the equation.

4x -2y = 18 ______1

-4x + 2y = -18 ____2

from (1) make y the subject of formular

4x -2y = 18

2y =  4x - 18

y = 2x - 9   ______3

substitute y = 2x - 9 into 2

-4x + 2y = -18

-4x + 2 (2x - 9 ) = -18

-4x + 4x - 18 = -18

-4x + 4x = -18 + 18

0 = 0

This gives no solution hence the simultaneous equation is said to be inconsistent
