Sagot :
Cevap:
Üsttekinin cvbı
7x/2-5=20-3x/2
7x/2+3x/2=20+5
5x=25 ten x=5
Alttakinin cvb
(x-3)/2-(10-5x)/5=1 paydaları 10 ile eşitle
5x-15-20+10x=10
15x=45 ten x=3
Adım adım açıklama:
7x/2 - 5 = 7x-10 / 2
20 - 3x/2 =40-3x/2
çaprazlama yapıyoruz
14x-20=80-6x
20x=100
x=5
2.'nin cevabı
5x-15-20+10x/10 = 1
yani
5x-15-20+10x=10
15x-35=10
15x=45
x=3
