Simplifying

2a + -5 = 8a + -11

Reorder the terms:

-5 + 2a = 8a + -11

Reorder the terms:

-5 + 2a = -11 + 8a

Solving

-5 + 2a = -11 + 8a

Solving for variable 'a'.

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

Add '-8a' to each side of the equation.

-5 + 2a + -8a = -11 + 8a + -8a

Combine like terms: 2a + -8a = -6a

-5 + -6a = -11 + 8a + -8a

Combine like terms: 8a + -8a = 0

-5 + -6a = -11 + 0

-5 + -6a = -11

Add '5' to each side of the equation.

-5 + 5 + -6a = -11 + 5

Combine like terms: -5 + 5 = 0

0 + -6a = -11 + 5

-6a = -11 + 5

Combine like terms: -11 + 5 = -6

-6a = -6

Divide each side by '-6'.

a = 1

Simplifying

a = 1
