Answer:

implifying

7(2a + 1) = 8

Reorder the terms:

7(1 + 2a) = 8

(1 * 7 + 2a * 7) = 8

(7 + 14a) = 8

Solving

7 + 14a = 8

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-7' to each side of the equation.

7 + -7 + 14a = 8 + -7

Combine like terms: 7 + -7 = 0

0 + 14a = 8 + -7

14a = 8 + -7

Combine like terms: 8 + -7 = 1

14a = 1

Divide each side by '14'.

a = 0.07142857143

Simplifying

a = 0.07142857143
