= y + v + z + v
= 2v + y + z
= 2(35) + 12 + z
= 70 + 12 + z
= 82 + z
= z + 82
= y × v - y + v
= 12 × 35 - 12 + 35
= 420 - 12 + 35
= 408 + 35
= 443

Soal 1
= y + v + z + v
= 2v + y + z
= 2(35) + 12 + z
= 70 + 12 + z
= 82 + z
= z + 82
Soal 2
= y × v - y + v
= 12 × 35 - 12 + 35
= 420 - 12 + 35
= 408 + 35
= 443
