Question

Cara penyelesaian Persamaan linear satu variabel di bawah ini...

5(x+4)+15=3(3x+1)

Answer 1

5(x+4) + 15 = 3(3x+1)
⇔5x + 20 + 15 = 9x + 3
⇔5x + 35 = 9x + 3
⇔5x - 5x + 35 - 3 = 9x - 5x + 3 - 3
⇔32 = 4x
⇔32 : 4 = x
⇔8 = x
HP = {x} = {8}

Answer 2

5(x+4)+15=3(3x+1)
5x+20+15=9x+3
5x+35=9x+3
5x-9x=3-35
-4x=-32
x=-32/-4
x=8
