supplement is two angle sun is 180
so 180-51=129
So we multiply both sides by 7 to make 2/7 a whole number. You get 2(4q+7/2)-21q=63. Then take 4q+7/2 out of parentheses and you get 8q+7-21q=63. Subtract 7 on both sides and add the q’s together, -13q=56. Divide both sides by -13 and you get around 4.3
For the first one the GCF is 4a and the seond one its 2d..
hope this helps
