The equation (2/5)*a - (3/4)*b = c solved for the variable a is:
a = (5/2)*(c + (3/4)*b)
Here we have the equation:
(2/5)*a - (3/4)*b = c
Where a, b, and c are variables.
Here we want to solve this equation for the variable a, this means that we need to isolate that variable in one side of the equation, so let's do that.
First, we need to remove the other term, then we can add its opposite in both sides of the equation so we get:
(2/5)*a - (3/4)*b + (3/4)*b = c + (3/4)*b
(2/5)*a = c + (3/4)*b
Now we need to remove the factor that multiplies the variable, we can do that by multiplying both sides of the equation by its inverse, whic is 5/2, if we do that we will get:
(5/2)*(2/5)*a = (5/2)*(c + (3/4)*b)
a = (5/2)*(c + (3/4)*b)
This is the equation solved for the variable a.
