Answer:
The answer to your question is x = 1 y = 1
Step-by-step 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
