- 2 x 1 )- 3 2x 5 ) 7
- 7x 1 2x 3 5
- 5 x 1 )- 3 2x 4 )= 4x 7
- Prove 3 x 1 )( x 7 )-( 2x 5 2 is never positive
- 7 x 2 2x 3 1 x 2 5x 6
- X x 1 3 2x 5 5 x 8 6 7
- (- x 7 )+ 5 3 1 2x 9
- 7 3 2x )+ 5 x 1 )= 34
- 5 2x 4 )= 7 x 1 )- 3
- X 7 )( 3 2x )+( 5x 2 )( 4x 1
- X 7 2x 5 1 x 3 3x 2 2
- 7 x 2 )+ 5 3 2x 1 )+ 1 how many solutions
