11-7x because eleven less than is 11- and seven times a number is 7x
Opposite angles are equal. An the angles on a straight line sum to make 180. As a result:
Y=105 z=75 x=75
Answer:
x = 3, y = 19
Step-by-step explanation:
x = 3, y = 4x + 7
Substitute x =3 into the second equation
y =4*3+7
y = 12 +7
y = 19
x = 3, y = 19
