Answer 1

Answer:

(13)

x= 8

y=11

(14)

x= 20

y=20.75

(15)

x=9

y=13

Step-by-step explanation:

(13) 8x-1 = 11x -25

24=3x

x= 8

8(8)-1 +15y-48= 180

15y=165

y=11

(14) 7x-44 + 4x + 4= 180

11x= 220

x= 20

4(20)+4+39= 8y-43

123=8y-43

166=8y

y=20.75

(15) 12x+1=15x-26

3x=27

x=9

28+15(9)-26+4y-9=180

4y=52

y=13

x=8 y=11 for the question 13
