Question

If G is the midpoint of FH find FGfg=11x-7 gh= 3x+9

Answer 1

Solution:

we are given that

If G is the midpoint of FH,  it mean that

$FG=GH$

we are also given that

$FG=11x-7 ,GH= 3x+9$

So we can write

$11x-7=3x+9\\ \\ 11x-3x=7+9\\ \\ 8x=16\\ \\ x=2$

So $FG=11x-7=11*\frac{1}{2}-7=11*2-7=15$
