Starting with this: [tex]3(2x + 4) = - 6[/tex] First you would distribute the 3 into the ( ) so 2 would become 6 and 4 would become 12 [tex]6x + 12 = - 6[/tex] next you subtract 12 from -6 [tex]6 x = - 18[/tex] now you divide -18/6 [tex] \frac{ - 18}{6} = - 3[/tex]
then for #3. [tex]3x - 3 = 13[/tex] the next step would be to add 3 to 13 [tex]3x = 16[/tex] then divide 3 from 16 to get [tex] \frac{16}{3} = 5.333333333[/tex] so around 5.3
