Y = \frac{1}{2}x + 3
y = x - 4

Since both equations are equal to y, you can set the two values equal to each other and solve for x.

\frac{1}{2}x + 3 = x - 4   Multiply both sides by 2
x + 6 = 2x - 8   Add x to both sides
6 = 3x - 8   Add 8 to both sides
14 = 3x   DIvide both sides by 3
4\frac{2}{3} = x

Now, plug the x value into one of the original equations, I'll plug it into y = x - 4.

y = x - 4   Plug in the x value 
y = 4\frac{2}{3} - 4   Subtract
y = \frac{2}{3}

x = 4\frac{2}{3} and y = \frac{2}{3}

OF bisects EOF. EOF=y+30 and FOG=3y-50. solve for y.
Alexeev081 [22]

It always helps to draw a picture. Given the information, Segment OF is the center line that is bisecting this angle.

Since it's bisecting (cutting in half)... we can simply set the two angles equal to each other.

y+30=3y-50
-2y+30=-50
-2y=-80
y = 40

C)40.
