Question

which is a simplified form of the expression 2c+2+6c-4

Answer 1

Simplifying
2c + 2 + 6c + -4 = 0

Reorder the terms:
2 + -4 + 2c + 6c = 0

Combine like terms: 2 + -4 = -2
-2 + 2c + 6c = 0

Combine like terms: 2c + 6c = 8c
-2 + 8c = 0

Solving
-2 + 8c = 0

Solving for variable 'c'.

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

Add '2' to each side of the equation.
-2 + 2 + 8c = 0 + 2

Combine like terms: -2 + 2 = 0
0 + 8c = 0 + 2
8c = 0 + 2

Combine like terms: 0 + 2 = 2
8c = 2

Divide each side by '8'.
c = 0.25

Simplifying
c = 0.25
