a.
[tex]147.3 - x = 89.52[/tex]
[tex] - x = 89.52 - 147.3[/tex]
[tex] - x = - 57.78[/tex]
[tex]x = 57.78[/tex]
b.
[tex]x - 27.3 = 186.72[/tex]
[tex]x = 186.72 + 27.3[/tex]
[tex]x = 214.02[/tex]
c.
[tex]43.7 - x + 123.45 = 156.327[/tex]
[tex]167.15 - x = 156.327[/tex]
[tex] - x = 156.327 - 167.15[/tex]
[tex] - x = - 10.823[/tex]
[tex]x = 10.823[/tex]
d.
[tex]236.7 + x = 333.12[/tex]
[tex]x = 333.12 - 236.7[/tex]
[tex]x = 96.42[/tex]
e.
[tex]x + 89.72 = 232.02[/tex]
[tex]x = 232.02 - 89.72[/tex]
