Question

X/9 -1=5 X=? 9y+1=7 Y=? 3z/7 + 3=-7 Z=

Answer 1

X/9 -1=5
X=?

9y+1=7
Y=?

3z/7 + 3=-7
Z=
X=54
Y=1/3
Z=-23 1/3

Answer 2

1.

x/9 -1 = 5

add 1 to both side of the equation

x/9 = 6

multiply both side of the equation by 9

x = 54

2.

9y + 1 = 7

subtract 1 from each side of the equation

9y = 6

divide both side of the equation by 9

y = $\frac{6}{9}$

divide the numerator and the denominator by 3 in order to simplify your fraction

y = $\frac{2}{3}$

3.

3z/7 + 3 = -7

subtract 3 from each side of the equation

3z/7 = -10

multiply both side of the equation by 7

3z = -70

divide both side of the equation by 3

z = $\frac{-70}{3}$

There you go! I really hope this helped, if there's anything just let me know! :)
