Question

solve for x (7x+14)/3 - (7-3x)/5 = 6x-(4x+2)/3 -5​

Answer 1

Answer:

$\frac{7x + 14}{3} - \frac{7 - 3x}{5} = \frac{6x - (4x + 2)}{3} - 5 \\ \\ \frac{5(7x + 14) - 3(7 - 3x)}{15} = \frac{ - 24x - 12x}{3} - 5 \\ \\ \frac{35x + 70 - 21 + 9x}{15} = \frac{ - 36x}{3} - 5 \\ \\ \frac{35x + 9x + 70 - 21}{15} = \frac{ - 36x}{3} - 5 \\ \\ \frac{44x + 49}{15} = \frac{ - 36x}{3} - 5 \\ \\ 3(44x + 49) = 15( - 36x) - 5 \\ \\ 132x + 147 = - 540x - 5 \\ \\ 132x + 540x = - 5 - 147 \\ \\672x = - 152 \\ \\ x = - \frac { 152}{672} \\ \\ x = - \frac{76}{336} \\ \\ x = - \frac{38}{168} \\ \\ x = - \frac{19}{84}$

Big Question but no worries I solved it correctly : )

Hope it helps to you!!

Answer 2

Answer:

Equation -: 35x^2 + 9x + 85 = 0

Step-by-step explanation:

Solve this Equation by quadratic formula method:

Then, we get Discriminant, D= b^2 - 4ac < 0

Therefore, x= - b/2a = -9/70

Hence, x = -9/70
