1) умножаем все уравнение на 15
4-7x+5*(1-x)=15*4-3(2x+1)
4-7x+5-5x=60-6x-3
-12x+9=57-6x
-12x+6x=57-9
-6x=48
x=-48:6
x= -8
===============
2) умнож. на 6
10-y+2*(3y+8)=3*(y+6)
10-y+6y+16=3y+18
5y+26=3y+18
5y-3y=18-26
2y=-8
y= -8:2
y= -4
================
3) умнож. на 20
4*(3x+5)+5*(9x-5)=6*20+10*(3x+1)
12x+20+45x-25=120+30x+10
57x-5=130+30x
57x-30x=130+5
27x=135
x=135:27
x=5
===============
4) умнож.на 8
5-9x-2*(3+5x)=4*(5-3x)
5-9x-6-10x=20-12x
-19x-1=20-12x
-19x+12x=20+1
-7x=21
x= -21:7
