Tolong kaka besok di kumpulkan
1.
[tex]180 = 90 + 2x + 3x[/tex]
[tex]180 = 90 + 5x[/tex]
[tex]180 = 5x + 90[/tex]
[tex]180 - 90 = 5x + 90 - 90[/tex]
[tex]90 = 5x[/tex]
[tex] \frac{90}{5} = \frac{5x}{5} [/tex]
[tex]x = 18[/tex]
Jadi, besar nilai x adalah 18.
2.
[tex]180 = 2y + 20 + 140[/tex]
[tex]180 = 2y + 160[/tex]
[tex]180 - 160 = 2y + 160 - 160[/tex]
[tex]20 = 2y[/tex]
[tex] \frac{20}{2} = \frac{2y}{2} [/tex]
[tex]y = 10[/tex]
Jadi, besar nilai y adalah 10.
3.
[tex]90 = 3b + 2b + 15[/tex]
[tex]90 = 5b + 15[/tex]
[tex]90 - 15 = 5b + 15 - 15[/tex]
[tex]75 = 5b[/tex]
[tex] \frac{75}{5} = \frac{5b}{5} [/tex]
[tex]b = 15[/tex]
Jadi, besar nilai b adalah 15.
