Step-by-step explanation:
2)
x + 14
= -0.87
x +
= - 
x +
= - 
x = -
-
x = - 
3)
x -8
= 1.5
x -
= 
x =
+ 
x = 
x = 
4)
x -
= - 7 
x -
= - 
x = -
+
x = - 
5)
- x = 6 
=
+ x
-
= x
-
= x
x = - 
6)
-33.754 - x = 28.05
-33.754 - 28.05 = x
- 61.804 = x
x = - 61.804
The equation is 
Step-by-step explanation:
Let us revise how to make a variable subject of an equation
- Write the equation and circle the variable you want to make it subject
- Keep it in one side and move all other in the other side
- Make the coefficient of the subject 1
∵ A =
× b × h
∵ b is the subject
∴ Multiply the two sides by 2
∴ 2A = b × h
- Divide both sides by h
∴ 
- Switch the two sides
∴ 
The equation is
