Solve for x in each of the equations or inequalities below, and name the property and/or properties used:
a. 3/4 x = 9
b. 10+ 3x = 5x
c. a + x = b
d. cx = d
e. 1/2 x - g < m
f. q + 5x = 7x - r

Respuesta :

Answer

a) 3/4 x = 9

    x = [tex]\dfrac{9\times 4}{3}[/tex]

    x = 12

b)  10+ 3x = 5x

     2 x = 10

        x = 5

c) a + x = b

       x = b - a

d) c x = d

      x =  [tex]\dfrac{d}{c}[/tex]

e)  [tex]\dfrac{1}{2} x - g < m[/tex]

     [tex]\dfrac{1}{2} x< m + g[/tex]

              x  < 2( m + g)

f) q + 5 x = 7 x - r

   q + r = 2 x

      [tex]x = \dfrac{q + r}{2}[/tex]
