Use substitution to solve. x-5y=2 and 9x+8=32y

x=-8,y=-2

Step-by-step explanation:

x=2+5 y

put value of x in eq 2

9(2+5 y)+8=32 y

18+45 y+8=32 y

26=32 y-45 y

26=-13 y

y=26/-13

y=-2

put value of y in eq x=2+5 y

x=2+5(-2)

x=2-10=-8

Step-by-step explanation:

slope = "rise over run" = 1.5/18 = 3/36 = 1/12 for the 1st section to the landing

slope is the change in height, the vertical change, divided by the change in horizontal distance

2nd section has slope 1/18 and covers 9 feet. That means it rises 1/2 foot

slope = 1/18 = (1/2)/9      

the door is 2 feet higher than the ground level,  1.5 + .5 = 2 feet change vertically

Sorry if I am wrong
