Question

2c+7n+z=y solve for c

Answer 1

Solving an equation

In order to solve for c we just have to remember one simple rule: what we do in one side of the equal "=" we should do it in the other side.

In this case:

2c + 7n + z = y

↓ substracting z both sides

2c + 7n + z - z = y - z

2c + 7n + 0 = y - z

2c + 7n = y - z

↓ substracting 7n both sides

2c + 7n - 7n = y - z - 7n

2c + 0 = y - z - 7n

2c = y - z - 7n

↓ dividing by 2 both sides

`\begin{gathered} (2c)/(2)=(y-z-7n)/(2) \\ c=(y-z-7n)/(2) \end{gathered}`

Then, we have the answer:

`c=(y-z-7n)/(2)`
