2a+2b/z=5c

solve for a

2a+2b

_______ = 5c

z

2a + 2b = (z)5c

2a = -2b + 5cz

2a/2 = -2b/2 + 5cz/2

a = -b + 5cz/2

multiply each term by z

2az + 2b = 5cz
2az = 5cz-2b
a = (5cz - 2b)/(2z)

To solve for a in the equation 2a + 2b/z = 5c, we can follow the steps below:

Step 1: Start by isolating the term with the variable a.
Subtract 2b/z from both sides to move the term to the right side of the equation:
2a = 5c - 2b/z

Step 2: Divide both sides of the equation by 2 to solve for a.
To do this, divide both sides of the equation by the coefficient of a (which is 2):
a = (5c - 2b/z) / 2

Therefore, the solution for a is:
a = (5c - 2b/z) / 2
