Уравнение 1) 9y+6=3y 2) 3x-1=5x 3) (7x-1) 3=5x
с решением
9y-3y=6
6y=6
y=1
2)3x-5x=1;-2x=1;x=-0,5
3)21x-3=5x;21x-5x=3;16x=3;x=5,3
1)9y-3y=6;6y=-6;y=-1;
1. 9y + 6 = 3y 9y – 3y = –6 6y = –6 y = –1 2. 3x – 1 = 5x 3x – 5x = –1 –2x = –1 x = 1/2 x = 0.5 3. (7x – 1) * 3 = 5x 21x – 3 = 5x 21x – 5x = 3 16x = 3 x = 3/16 x = 1/4 x = 0.25
1) y = -1 2) x = -1/2 3) x = 3/16
