Cześć!

1)

[tex](6y-2):(-4)=8 \ \ /\cdot(-4)\\\\6y-2=-32\\\\6y=-32+2\\\\6y=-30 \ \ /:6\\\\\boxed{y=-5}[/tex]

2)

[tex]12-(-2b)=88\\\\12+2b=88\\\\2b=88-12\\\\2b=76 \ \ /:2\\\\\boxed{b=38}[/tex]

3)

[tex]-4\cdot(c-17)=-48 \ \ /:(-4)\\\\c-17=12\\\\c=12+17\\\\\boxed{c=29}[/tex]

[tex](6y - 2) : (-4) = 8 \ \ |*(-4)\\\\6y-2=-32\\\\6y=-32+2\\\\6y=-30\ \ |:6\\\\y=-5[/tex]

[tex]12 - (-2b) = 88\\\\12+2b=88\\\\2b=88-12\\\\2b=76\ \ |:2\\\\b=38[/tex]

[tex]-4 * (c - 17) = -48\\\\-4c+68=-48\\\\-4c=-48-68\\\\-4c=-116\ \ |:(-4)\\\\c=29[/tex]
