Subtract the numbers

\frac{7}{2}

\frac{7}{2} - A

\frac{7}{2} - A = 0

Move the constant to the right-hand side and change its sign

- A = 0 - \frac{7}{2}

Removing 0 doesn't change the value,so remove it from the expression

- A = - \frac{7}{2}

Solution

A = \frac{7}{2}

Alternative Form

A = 3.5
