What is the solution of the equation 2/5x+4=1/5 ?
To solve the equation, we can start by isolating the variable x.
2/5x + 4 = 1/5
Subtract 4 from both sides:
2/5x = 1/5 - 4
To add or subtract fractions, we need a common denominator, which in this case is 5:
2/5x = 1/5 - 20/5
2/5x = -19/5
Now, to solve for x, we can multiply both sides by the reciprocal of 2/5, which is 5/2:
x = (-19/5) * (5/2)
This simplifies to:
x = -19/2
