Question

Solve the equation

a = 2

Evaluate

9 = 8 a - 7

Swap the sides of the equation

8 a - 7 = 9

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

8 a = 9 + 7

Add the numbers

8 a = 16

Divide both sides

\frac{8 a}{8} = \frac{16}{8}

Divide the numbers

a = \frac{16}{8}

Solution
