1. 19-3x=2x+9

Ditanya:nilai x?

= 19-3x=2x+9

= -3x+19= 2x+9

= -3x+19-19=2x+9-19

= -3x= 2x-10

= -3x-2x= 2x-10-2x

=-5x= -10

[tex] \frac{ - 5x}{ - 5x} = \frac{ - 10x}{ - 5x} = 2[/tex]

X= 2

2.7-4y=-8-y

= 7-4y= -8-y

= -4y+7= -8-y

Tahap dua

= -8-y

=-y-8

= -4y+7-7=-y-8-7

=-4y=-y-15

= -4y+y=-y-15+y

= -3y= -15

=

[tex] \frac{ - 3y}{ - 3} = \frac{ - 15}{ - 3} = y = 5[/tex]

y= 5
