x/5y + 2x/3y = 3x/15y + 10x/15y = 13x/15y
x=20 y=-3
4y
I'm assuming you mean 15y+10x=12? ... That'd be y=-5/3x+12/15
6y3 + 8y2 - 15y - 20 is an expression, not an equation (or inequality). An expression cannot be solved.The expression factorises to (3y + 4)*(2y2 - 5)
- 3X - (- 4X) is the same as - 3X + 4X X(- 3 + 4) that is all the factoring needed there
x/5y + 2x/3y = 3x/15y + 10x/15y = 13x/15y
x=20 y=-3

Multiply the first equation by 3 to give 9x + 15y = 21
It is two terms of an algebraic expression in the form of: x-15y
If that's 3x2, the answer is (x + 1)(3x - 5)
(3x+1)(x-2)
Elimination is the removal of undigested food (solid waste) from the body.
Solve by factoring.2x2 - 3x + 1 = 0
