РЕШИТЕ УРАВНЕНИЕ 5х * (12х + 7 ) - 4х * (15х - 11)= 10+29х. 6y*(13y-9)-13y*(6y-1)=24y+13...

1. 5x(12x+7)-4x(15x-11)=10+29x
60x²+35x-60x²+44x=10+29x
79x=10+29x
79x-29x=10
50x=10
x= $\frac{10}{50} = \frac{1}{5} =0.2$

2.6y(13y-9)-13y(6y-1)=24y+13
78y²-54y-78y²+13y=24y+13
-41y=24y+13
-41y-24y=13
-65y=13
y= $-\frac{13}{65} =- \frac{1}{5} = -0.2$

3. $\frac{x}{5} - \frac{x}{6} = 0.1$
$\frac{x}{5} - \frac{x}{6} = \frac{1}{10}$
$30* \frac{x}{5} -30* \frac{x}{6} =30* \frac{1}{10}$
6x-5x=3
x=3
