Answer 1

Answer:

Simplifying

4a + -10 = 2a

Reorder the terms:

-10 + 4a = 2a

Solving

-10 + 4a = 2a

Solving for variable 'a'.

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

Add '-2a' to each side of the equation.

-10 + 4a + -2a = 2a + -2a

Combine like terms: 4a + -2a = 2a

-10 + 2a = 2a + -2a

Combine like terms: 2a + -2a = 0

-10 + 2a = 0

Add '10' to each side of the equation.

-10 + 10 + 2a = 0 + 10

Combine like terms: -10 + 10 = 0

0 + 2a = 0 + 10

2a = 0 + 10

Combine like terms: 0 + 10 = 10

2a = 10

Divide each side by '2'.

a = 5

Simplifying

a = 5
