(2 x + 1):15=(x-1):7
7(2x+1)=15(x-1)
14x+7=15x-15
14x-15x=-15-7
-x=-22
x=22

Answer:
m<F = 53
Step-by-step explanation:
Exterior angles thm:
5x - 10 + 3x + 14 = 100
8x + 4 = 100
8x = 104
x = 13
m<F:
3x + 14
3(13) + 14
39 + 14
53
<span>3x- 1/9 y=18
</span><span>3x- 1/9(27) =18
3x - 3 = 18
3x = 21
x = 7
