Given the numerical equation:
2x-4/10x+2=3\5
Determine the value of x.
Solution:
In order to determine the value of x, we can start first by cross multiplying, so that we can cancel the denominator.
2x-4/10x+2=3\5
5(2x-4)=3(10x + 2)
10x - 20 = 30x + 6
Transpose 10x and 6 to the opposite sides of their equation, hence in tranposing a number, it must be taken to note that the sign changes.
30x - 10x = -20 -6
20x = -26
Divide both sides by 20 in order to find the value of x.
x = -26/20
x = -13/10
Final answer:
x = -13/10
