B. Since that is supplementary we know that’s 180. 180-51=129. Now let’s do 14x-25=129. Add 25 both sides now u get 14x=154. Divide by 14 on both sides. X=11

C. We know they are vertical angels so they are equal to each other. 10x-26=7x+10. Subtract 7x and add 26. That would give u 3x=36.
X=12

D. We know it’s supplementary which equals 180. 2x+70+101-5x=180. Combine like terms. -3x+171=180. Subtract 171 on both sides. Now it’s -3x=9. Divide by -3 and u get -3.
X=-3

Hope this helps :)
