a.
x + 1/2 = 3/5
x = 3/5 - 1/2
x = 1/10
b.
1/2 + p = 4/9
p = 4/9 - 1/2
p = -1/18
c.
1 + I = 4/9
I = 4/9 -1
I = -5/9
d.
g - ( -1, 258) = 2, 365
g + 1, 258 = 2,365
g = 2, 365 - 1, 258
g = 1, 107
e.
y + (-3/7) = 1/7
y - 3/7 = 1/7
y = 1/7 + 3/7
y = 4/7
f.
1/5 + (-2/3) = u
1/5 - 2/3 = u
-7/15 = u
g.
c + 0 = -5/7
c = [tex]\bold{-\dfrac{5}{7}}[/tex]
h.
t - 11/6 = 1/3
t = 1/3 + 11/6
t = 13/6
