Penyelesaian soal :

[tex] \sf 9(5x - 7) = 4(5x + 35)[/tex]

[tex] \sf45x - 63 = 4(5x + 35)[/tex]

[tex] \sf45x - 63 = 20x + 140[/tex]

[tex] \sf45x - 63 - 20x = 140[/tex]

[tex] \sf45x - 20x = 140 + 63[/tex]

[tex] \sf25x = 140 + 63[/tex]

[tex] \sf25x = 203[/tex]

[tex] \sf x = \frac{203}{25} [/tex]
