43 = 2x + (3x + 1) + (4x - 1)
43 = 2x + 3x + 1 + 4x - 1
43 - 1 + 3 = 2x + 3x + 4x
45 = 9x
5 = x
2x = 2(5)
= 10 cm
3x + 1 = 3(5) + 1
= 15 + 1
= 16 cm
4x - 3 = 4(5) - 3
= 20 - 3
= 17 cm
Jadi panjang sisi terpendeknya adalah 10 cm.
9x -2 = 43
9x = 43+ 2
9x = 45
x = 5
maka sisi terpendek = 2x = 2.5 = 10
