Question

Find

Answer 1

Step-by-step explanation:

$4 {x}^{2} + 5x + 6x = 3x - 2 {x}^{2} + x \\ 4 {x}^{2} + 11x = 4x - 2 {x}^{2} \\ 4 {x}^{2} + 2 {x}^{2} = 4x - 11x \\ 6 {x}^{2} = - 7x \\ 6x = - 7 \\ x = \frac{ - 7}{6} \\ thank \: you$

Answer 2

Answer:

$\rm x = -\frac{7}{6}$

Step-by-step explanation:

$\rm 4 {x}^{2} + 5x + 6x = 3x - 2 {x}^{2} + x$

$\rm 4x^{2}+11x=3x^{1}-2x^{2}+x$

$\rm 4x^{2}+11x=3x-2x^{2}+x$

$\rm 4x^{2}+11x=4x-2x^{2}$

$\rm 4x^{2}+11x-4x=-2x^{2}$

$\rm 4x^{2}+7x=-2x^{2}$

$\rm 4x^{2}+7x+2x^{2}=0$

$\rm 6x^{2}+7x=0$

$\rm 6x + 7 = 0$

$\bold{x = -\frac{7}{6}}$
