Question

resolver paso a paso el método de cramer de - 3x - 3y=-18 4x - 6y = 14 paso a paso​

Answer 1

Explicación paso a paso:

-3x- 3y = 18

4x-6y= 14

∆s =| -3 3|. ∆s = -3× (-6) -( 4 ×(- 3)

| 4 -6|. 18 -(- 12) = 30

∆s= 30

∆x = 18 -3 ∆x = 18× 6 -(- 3×14

14. -6. -108- (-42 = -66

∆x = -66

∆y = -3. 18 ∆y = -3 × 14 - 18 × 4

4. 14 -42 - 72 = -114

∆y = -114

x = -66÷30 = -2.2

y = 114 ÷ 30 = -3.8
