Answer:

4th option

Step-by-step explanation:

Given

\frac{x}{x^2+3x+2} - \frac{1}{(x+2)(x+1)} ← expand denominator using FOIL

= \frac{x}{x^2+3x+2} - \frac{1}{x^2+3x+2}

Since the denominators are common, then subtract the numerators

= \frac{x-1}{x^2+3x+2}

Step-by-step explanation:

<u>Statement                                                        Reason                               </u>

∠5 and ∠7 are vertical angles                        Vertical angles theorem

m∠5 = m∠7                                                      Definition of vertical angles

m∠5 = -2(3x - 4), m∠7 = 3(x - 3) - 1                  Given

-2(3x - 4) = 3(x - 3) - 1                                       Substitution property of equality

-6x + 8 = 3x - 9 - 1                                            Distributive property

3x + 6x = 8 + 10                                               Addition property

9x = 18                                                              Addition property

x = 18/9                                                             Division property

x = 2                                                                  Proved

Solve 63 minus X equals 62 for x
r-ruslan [8.4K]

Answer:

x=1

Step-by-step explanation:

This stuff is quite easy in reality. Here's a little example including your numbers.

63-x=62; solve for x\\\\63-x-63=62-63\\\\-x=1\\

by this point we are left with simplifying it. Since it's a double negative we get a positive. Thus x=1
