Answer:

Step-by-step explanation:

4x + 23 + 9x - 38 = 180

13x - 15 = 180

13x = 195

x = 15

4(15) + 23= 60 + 23= 83

9(15) - 38 = 135 - 38= 97

21y - 1 + 97 = 180

21y + 96 = 180

21y = 84

y = 4

21(4) - 1 = 84 - 1 = 83

Answer:

4x+23+9x-38=180linear pair

13 x=180+15

x=195/13=15

again

4x+23=21y-1alternate angle

5×15+23=21y-1

83+1=21y

y=84/21=4 therefore value of y is 4
