Answer:
(x,y): (6 , -3) or (-30/7 , 33/7)
Step-by-step explanation:
6x + 8y = 12
x = y + 9 or y = x+ 9
if x = y+9
6*(y+9) + 8y = 12
14y = -42
y = -3 and x = 6
if y = x+9
6x + 8*(x+9) = 12
14x = -60
x = -30/7 and y = 33/7

Answer:
57 years old
Step-by-step explanation:
If two-thirds of a woman's age is 38, then:
(2/3)x = 38
Multiplying both sides by 3/2 to solve for x will give us her age:
3/2)(2/3)x = (3/2)*38
x =57
She is 57 years old.
