Germany was the first European country to participate in slave trade
-2.5, -1.1, -4/5, 0.8, 9/5
By solving the linear equation it can be obtained that
The value of x is 2
What is a linear equation?
At first it is important to know about equation
Equation shows the equality between two algebraic expressions by connecting the two algebraic expressions by an equal to sign.
A one degree equation is known as linear equation.
The given linear equation is
0.3 = 0.5x - 0.7
0.5x = 0.3 + 0.7
0.5x = 1
x = 
x = 2
The solution of this linear equation is x = 2
