Question

1)54-15x=3x-3,6
2)0,2(7-2y)=2,3-0,3(y-6)
3) 6,2(3-2x)=20-(12,4x+1,4)
4)3/8x+15=1/6x+10
5)3x+6=2(2x-7)-x

Answer 1

1)54-15x=3x-3,6; 57,6=18x=3,2
2)0,2(7-2y)=2,3-0,3(y-6); 1,4-0,4y=2,3-0,3y+1,8=
-2,7=0,1y; y=(-27)
3)6,2(3-2x)=20-(12,4x+1,4); 18,6-12,4x=20-12,4x-1,4; 0=0x
4)3/8x+15=1/6x+10; 5/12=-5=65/12
5)3x+6-4x+14+x=0; 0x=-20
