Answer:

x = 9

y = 3

Step-by-step explanation:

2x + 2y = 24 is the same as x + y = 12

using substitution, x = 12-y

12 - y = 3y

12 = 4y

y = 3

x = 3(3)

x = 9

40° 87° Xº Q Image not to scale 38° Calculate the missing internal angle x.

bagirrra123 [75]

Q = 87 + 40

Q = 127

X + 127 + 38 = 180

X = 180 - 127 - 38

X = 15

Therefore we say X is 15
