Jackie is solving this system of linear equations.
3x + 2y = 20
4x - y = 30

Answer 1

Respuesta:

resolver(4x−y=30)

=resolver(4⋅x−y=30;x)

=[30+y4]

=30+y4

resolver([30+y4])

=resolver(30+y4;y)

=[−30]

=−30

resolver(3⋅x+2⋅y=20)

=resolver(3⋅x+2⋅y=20;x)

=[20−2⋅y3]

=20−2⋅y3

resolver([20−2⋅y3])

=resolver(20−2⋅y3;y)

=[10]

=10
