Q1.
[tex]x + 20 = - 32[/tex]
Add -20 to both sides of the equation.
[tex]x + 20 - 20 = - 32 - 20[/tex]
Simplify
[tex]x = - 52[/tex]
Q2.
[tex]w + 10 = 25[/tex]
Add -10 to both sides of the equation.
[tex]w + 10 - 10 = 25 - 10[/tex]
[tex]w = 15[/tex]
Q3.
[tex]7.2 + b = 12[/tex]
Add -7.2 to both sides of the equation.
[tex] - 7.2 + 7.2 + b = 12 - 7.2[/tex]
[tex]b = 4.8[/tex]
Q4.
[tex]5.3 + s = 15[/tex]
Add -5.3 to both sides to get,
[tex]s + 5.3 - 5.3 = 15 - 5.3[/tex]
Simplify:
[tex]s = 9.7[/tex]
Q5.
[tex]p + ( - 25) = - 10[/tex]
Add 25 to both sides,
[tex]p - 25 + 25 = - 10 + 25[/tex]
[tex]p = 15[/tex]
Q6.
[tex]m + - 1.6 = -4.8[/tex]
Add 1.6 to both sides of the equation;
[tex]m + - 1.6 + 1.6 = - 4.8 + 1.6[/tex]
[tex]m = - 3.2[/tex]
