if EG=67 we have (3x+7)+(5x-4)=67 let's simplify [tex]67 = (3x + 7) + (5x - 4) \\ 67 = 8x + 3 \\ 64 = 8x \\ \frac{64}{8} = x \\ 8 = x[/tex] now we know x is 8 we can use this to find EF since EF=3x+7 [tex]3(8) + 7 = 24 + 7 = 31[/tex] so we have EF is 31! if.you like my answer please rate Brainliest
