Hi Rarinstraw,
This is the BEST way to do it :)
(2x+1)3+(5x−2)2−(3x−3)5=2Multiply through by the lowest common multiple - that is 3030(2x+1)3+30(5x−2)2−30(3x−3)5=6010(2x+1)1+15(5x−2)1−6(3x−3)1=6010(2x+1)+15(5x−2)−6(3x−3)=60See that got rid of all the fractions :)20x+10+75x−30−18x+18=6020x+75x−18x+18+10−30=6077x−2=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)
