I NEED HELP.<br>Consider the figure below.<br>Find the value of x,y and z​
Andrews [41]

Answer:

x= 7

y=9

z=90

Step-by-step explanation:

8x = (9x-7)

8x = 9x-7

8x - 9x= -7

-x= -7

<em>(multiply -1 to each side to make it positive)</em>

x= 7

(5y-11)+(9x-7)=90

5y-11+9(7)-7=90

5y-11+63-7=90

5y+63-18=90

5y+45=90

5y=90-45

5y=45

y=45÷5

y=9

(5y-11)+8x+z=180

5y-11+8x+z=180

5(9)-11+8(7)+z=180

45-11+56+z=180

34+56+z=180

90+z=180

z=180-90

z=90
