Question

Solve for x in each of the equations or inequalities below, and name the property and/or properties used:

Answer 1

Answer

a) 3/4 x = 9

    x = $\dfrac{9\times 4}{3}$

    x = 12

b)  10+ 3x = 5x

     2 x = 10

        x = 5

c) a + x = b

       x = b - a

d) c x = d

      x =  $\dfrac{d}{c}$

e)  $\dfrac{1}{2} x - g < m$

     $\dfrac{1}{2} x< m + g$

              x  < 2( m + g)

f) q + 5 x = 7 x - r

   q + r = 2 x

      $x = \dfrac{q + r}{2}$
