Hi Rarinstraw,

 

This is the BEST way to do it :)

 

(2x+1)3+(5x2)2(3x3)5=2Multiply through by the lowest common multiple - that is 3030(2x+1)3+30(5x2)230(3x3)5=6010(2x+1)1+15(5x2)16(3x3)1=6010(2x+1)+15(5x2)6(3x3)=60See that got rid of all the fractions :)20x+10+75x3018x+18=6020x+75x18x+18+1030=6077x2=6077x=62x=6277

2/3x + 1/3 + 2 1/2x - 1 - 3/5x - 3/5 =2

 

Combine like terms.

 

The decimals are approximate, the numbers would have repeated for ages otherwise.

 

2.57x - 1.26 = 2

 

Add 1.26 to both sides.

 

2.57x=3.26

 

2.57x=3.26 = x=(326/257)
