Question

Geometry Question!! One problem. Please expain fully. Answer is know, but the work to the answer is needed. #19 only~~~

Answer 1

#19. I also got 29,28
4x+ 2x+6= 180 cuz consecutive angles equal 180
6x+6= 180
Subtract 6
6x= 174
Divide by 6
X=29

3y-20+4y+4=180
7y-16=180
Add 16
7y= 196
Divide by 7
Y= 28

Answer 2

$\bf \begin{array}{llrll} -2x+3y=26&\implies &-2x+3y=26\\ x-y=1&\times 2\implies &2x-2y=2\\ &&-------\\ &&0x+1y=28 \end{array} \\\\\\ \boxed{y=28}\qquad thus\implies x-y=1\implies x=1+y\implies \boxed{x=29}$
