Question

What's the solution to this system of linear equations?

7x - 2y = -6
8x + y = 3

A. (-6,c3)

B. (0, 3)

C. (15, -1)

D. (1, -5)

Any help is appreciated :)

Answer 1

Option B. (0,3) is the correct answer

Step-by-step explanation:

Given equations are:

7x - 2y = -6    Eqn 1

8x + y = 3     Eqn 2

Multiplying Equation 2 by 2

$2*(8x + y) = 2*3 \\16x+2y=6\ \ \ \ Eqn\ 3$

Adding Eqn 1 and Eqn 3

$7x-2y+(16x+2y)=-6+6\\7x-2y+16x+2y=0\\23x=0\\x=0$

Putting x=0 in Eqn 2

$8(0) + y = 3\\0+y=3\\y=3$

Hence,

Option B. (0,3) is the correct answer
