Solving for y in (-2/5)y = 4
This equation represents a simple linear equation where we need to isolate the variable 'y'. Let's follow these steps to solve for y:
1. Multiply both sides by the reciprocal of (-2/5)
The reciprocal of (-2/5) is (-5/2). Multiplying both sides of the equation by (-5/2) will eliminate the fraction in front of 'y'.
(-5/2) * (-2/5)y = 4 * (-5/2)
2. Simplify the equation
Simplifying both sides, we get:
y = -10
Solution:
Therefore, the solution to the equation (-2/5)y = 4 is y = -10.
This means that if we substitute y = -10 back into the original equation, the equation will hold true.
