What is the solution to the equation 3/m+3-m/3-m=m^2+9/m^2-9

Bas_tet [7]

Answer:

no solution

Step-by-step explanation:

If we subtract the left side of the equation, we get ...

$\dfrac{m^2+9}{m^2-9}-\dfrac{3}{m+3}+\dfrac{3}{3-m}=0\\\\\dfrac{m^2+9-3(m-3)-3(m+3)}{(m-3)(m+3)}=0\\\\\dfrac{m^2-6m+9}{(m-3)(m+3)}=0=\dfrac{(m-3)^2}{(m-3)(m+3)}\\\\\dfrac{m-3}{m+3}=0\quad\text{m$\ne$3}$

This equation will equal zero only if m=3, which is disallowed because it makes the denominator zero. Thus, there is no solution.

List all the elements of each set. Set of the values of x that turn equation 0.7(x−7)−4.9=5.7 into a true statement

Paraphin [41]

Answer: 22.14 (22.1428571429)

Step-by-step explanation:

Let's Start with the equation

0.7(x−7)−4.9=5.7

Add 4.9 to both sides

0.7(x-7)=10.6

Divide both sides by 0.7

x-7= 15. 1428571429

Add 7 to both sides

x= 22.1428571429 or 22.14
