The solution of the equations are given below.
What is an equation?
An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
The given equations are b + 6 = 15, 17.5 - b = 12.5, 4.b = 14, 3/2 + b = 5 and 27/b = 3.
Solve the equations one by one.
b + 6 = 15
Solve the equation,
b = 15 - 6
b = 9
17.5 - b = 12.5
Solve the equation,
b = 17.5 - 12.5
b = 5
4.b = 14
Solve the equation,
b = 14/4
b = 7/2
3/2 + b = 5
Solve the equation,
b = 5 - 3/2
b = 7 / 2
27/b = 3
Solve the equation
b = 27/3
b = 9
Equation 17.5 - b = 12.5 gives value 5.
Equations b + 6 = 15 and 27/b = 3 gives value 9.
And equations 4.b = 14 and 4.b = 14 gives value 7/2.
