Answer:
Step-by-step explanation:
you divide the two to the y, which is x=3/2y
then, you simplify the second equation to y, which is -3y= -4x+12
then, you substitute the x=3/2y into the second equation,
-3y = -6+12
-3y = 6
y = -2
Substitute the y into the first equation, x= 3/2y,
x = -3

Angle ∠ A = α = 25.385° = 25°23'6″ = 0.443 rad
Angle ∠ B = β = 73.004° = 73°14″ = 1.274 rad
Angle ∠ C = γ = 81.611° = 81°36'41″ = 1.424 rad

Since Jamie and Ana have the same age, they are both x years old. So x+x=2x.
