It is: 4x -34x^2 -21 simplified
-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
4x + 3y - 2x - 7y2x - 4y
Simplify 4x + 3 = 2x + 8 2x = 5 x =2½
If: 4x+(-12) = 8 then 4x = 20 and x = 5
9x2+9x-12 All I can do is simplify this. I can't solve it unless turn this expression into an equation.
2x + 4x + 3 = 6x + 3
It is: 4x -34x^2 -21 simplified
This would simplify as 4x-5
x2 + 4x = x(x+4)
6x-2y
6x plus 4y
-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
y-5x
4x + 3y - 2x - 7y2x - 4y
2x over 11
6x - 12 + 4x + 5 = 06x + 4x = 12 - 510x = 7x = 7/10
