With solving rational equations! i am no good at it : ( solve for x: 2 over 5 plus 3 over 5 x equals quantity x plus 5 over 10. (2 points) x = -3 x = 2 x = -3 and x = 2 no solution

If this is your equation: 
Solution:
LCD for 5 and 5x is 5x



 ←cross product
20x + 30 = 5x² + 25x  ←simplify with distributive property
0 = 5x² + 5x - 30 ←use inverse operations to collect all terms on one side
0 = x² + x - 6  ←if possible divide by numerical GCF (This case 5)
0 = (x + 3)(x - 2) ←Factor
x = -3 or x = 2
Please check by substitution in original equation... Both work
