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

How many solutions does this system of equations have?

Alekssandra [29.7K]

The first step for solving this expression is to know that since both of the expression are equal to y,, we must set them each to each other to form an equation in x. This will look like the following:
-3x + 7 = -3x - 6
Now cancel equal terms on both sides of the equation.
7 = -6
This tells us that the statement is false for any value of x and y,, so our answer is (x,y) ∈ ∅,, or no solution (option D).
Let me know if you have any further questions.

Solve by the linear combination method (with or without multiplication).

Dima020 [189]

The first step is to name the equations to make the process of solving them easy.

$6x+7y=-4....(1)\\5x-3y=-21....(2)$

The second step is to multiply each of the equations by the coefficient of the x term in the other equation. In this case, we will multiply equation (1) by 5 to get equation (3) and then multiply equation (2) by 6 to get equation (4).

$-30x-35y=20...(3)\\30x-18y=-126...(4).$

The next step is to add equation equation(3) and (4) together to get equation (5) as shown below;

$-53y=-106....(5)\\=> y= 2.$

The next step is to take the value of y and substitute it into any of the equations above. For this solution, I pick equation (1). The work done to solve for x is shown below.;

$6x+7y=-4\\=>6x+7(2)=-4\\=>6x=-18\\=>x=-3$

The solution for this system of equations is $(-3,2)$
