The linear combination method gives a solution of (–4, 2) for which of these systems of linear equations?

Step-by-step explanation:

See Attachment for complete question

To determine which of the options has (-4,2) as its solution; we have to test each linear combination until we arrive at an answer;

Given that

Testing Option A

Substitute and in

Open Brackets

Substitute and in

Open Brackets

In both cases, the expression on the right hand side equates to that on the left hand side;

Hence, there's no need to check for other options.

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
