bantuin nihh soal mtk susahhhhhhhhhhh

cari nilai a
[tex]a + 2 + 2a = 5 \\ 3a + 2 = 5 \\ 3a = 5 - 2 \\ 3a = 3 \\ a = 1[/tex]


cari nilai b
[tex]1 - 3b + b - 3 = 6 \\ - 2 - 2b = 6 \\ - 2b = 6 + 2 \\ - 2b = 8 \\ b = \frac{8}{ - 2} = - 4[/tex]
maka nilai
[tex]a + b = 1 + ( - 4) = - 3[/tex]



semoga terbantu
