Answer:

The answer to your question is x = 1 y = 1

Explanation:

Data

-2x + 6y = 4 Equation l

5x + y = 6 Equation ll

Process

1.- Calculate Δ

Δ = | -2 6 |

| 5 1 | = (-2 x 1) - (5 x 6)

= -2 - 30

= - 32

2.- Calculate Δx

Δx = | 4 6 |

| 6 1 | = (4 x 1) - (6 x 6)

= 4 - 36

= -32

3.- Calculate Δy

Δy = | -2 4 |

| 5 6 | = (-2 x 6) - (5 x 4)

= -12 -20

= -32

4.- Find x and y

x = Δx/Δ = -32/-32 = 1

y = Δy/Δ = -32/-32 = 1
