3x+7+5x-4=67
8x+3=67
8x=64
x=8, now sub 8 for x
3(8)+7
24+7=31
Answer:EF=31
Answer:

Step-by-step explanation:
Factorise the denominator of the second fraction
y² - 1 = (y - 1)(y + 1) ← difference of squares
To obtain a common denominator
multiply numerator/ denominator of first fraction by (y + 1)
=
-
← subtract numerators leaving the common denominator
= 
= 
=
← cancel common factor (y - 1) on numerator/denominator
=
