Answer 1

1.
( x - 5 ) / x - 1 = ( x + 3 ) / x / · x ( we will multiply both sides by x )
x - 5 - x = x + 3
- x = 3 + 8
- x = 8
x = - 8
Answer: D ) 8
2.
2/(8 x²) = 1/ 8 x / · x
2 / 8 x = 1 / 8
8 x = 16
x = 16 : 8
x = 2
Answer: D ) 2
3.
( x + 4 )/ x + 1 = ( x + 6 ) / x / · x
x + 4 + x = x + 6
x = 6 - 4
x = 2
Answer: B ) 2
4.
1 / 6 = 3 / ( x + 12 )
x + 12 = 18
x = 18 - 12
x = 6
Answer: A ) 6
