Question

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

Answer 1

The solution (-4,2) satisfies for the system of linear equations 3x + 13y = 14; 6x + 11y = -2

Step-by-step explanation:

Step 1:

Given detail is the solution of the equations (-4, 2) ie, x= - 4 and y = 2

This implies that this solution should satisfy the given linear equations.

Step 2:

Substitute values of x and y in the equations and verify whether the right hand side equals the left hand side.

System 1 Eq(1) ⇒ LHS = 3(-4) + 13 (2) = -12 + 26 = 14 = RHS

System 1 Eq(2) ⇒ LHS = 6(-4) + 11(2) = -24 + 22 = -2 = RHS

Therefore, the first system of linear equations satisfy the condition.
