Determine for what x fraction
9x68x8 \dfrac{ 9x -6 }{ 8x -8 }
:

Result

equals to 0:  0.67
equals to 10:  1.04
does not make sense:  1

Solution:

x1=(6)9=0.67x_1 = \dfrac{ -(-6)}{ 9} = 0.67
x2=10(8)(6)9108=1.04x_2 = \dfrac{ 10\cdot (-8)-(-6)}{ 9-10\cdot 8} = 1.04
x3=(8)8=1x_3 = \dfrac{ -(-8)}{ 8} = 1
