$$6/7z + 9/14=6 $$ first i found the common denominator which was 14 and multiplied the denominator 7 * 2 and the numerator i then multiplied 6 * 14 and got 84 which left me with 12z+9= + or - 84

dumbcow · Answer

$$\frac{6}{7}z+\frac{9}{14} = 6$$
subtract 9/14 on both sides
$$\frac{6}{7}z = \frac{84}{14} - \frac{9}{14} = \frac{75}{14}$$
multiply by 7/6 on both sides
$$z = \frac{75}{14}*\frac{7}{6} = \frac{25}{4} = 6.25$$

anonymous · Answer

yeah, or -6/7z -9/14 = 6
z = -7 3/4 = -7.75

We did it :D
