1.) 4=-6v+5v combine like terms -6v=5v=-1v rewrite 4=-1v divide -1 from both sides 4/-1=-4 rewrite v=-4
2.) -7(3r+6)=7(7r+4) we r goin to have to distribute -7(3r)=-21r -7(6)= -42 same for the other side 7(7r)=49r 7(4)=28 rewrite
-21r-42=49r+28 add 42 to both sides 28+42=66 rewrite -21r=49r+66 subtract 49r from both sides -21r-49r=-70r rewrite -70r=66 divide -70 from both sides 66/-70=-0.94 r=-0.94
hope this helps have a nice nite
