yarga [219]

Answer:

X = 18

Y = 18

Step-by-step explanation:

first make two equation like

x + y = 36

1180x + 125y = 23490

from equation one we have

y = 36- x

put in second equation

1180x + 125 (36-x) = 23490

1180x + 4500-125x = 23490

1055x = 23490-4500

x = 18990/1055

x = 18

put this x value in equation 1 to find y value

18+ y = 36

y = 36-18

y = 18
