3x + 2y = 16
4x - y =29
i managed to get x but i cant seem to get y right

You found x, right?

Now, plug the value of x into either of the given equations to find y.

I found x to be 7 and y to be -1.

We can also express the answer as

(x, y) = (7, -1).

  (x, y) = (6 8/11, -2 1/11)

Step-by-step explanation:

Add twice the second equation to the first:

  (3x +2y) +2(4x -y) = (16) +2(29)

  11x = 74 . . . . simplify

  x = 74/11 = 6 8/11

Substitute this into the second equation to find y.

  4(74/11) -y = 29

  (26 10/11) - 29 = y = -2 1/11

The solution is (x, y) = (6 8/11, -2 1/11).

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
