What is 2r + 8 > 16 - 2r?

Simplifying 2r + 8 = 16 + -2r

Reorder the terms: 8 + 2r = 16 + -2r

Solving 8 + 2r = 16 + -2r

Solving for variable 'r'. Move all terms containing r to the left, all other terms to the right.

Add '2r' to each side of the equation. 8 + 2r + 2r = 16 + -2r + 2r

Combine like terms: 2r + 2r = 4r 8 + 4r = 16 + -2r + 2r

Combine like terms: -2r + 2r = 0 8 + 4r = 16 + 0 8 + 4r = 16

Add '-8' to each side of the equation. 8 + -8 + 4r = 16 + -8

Combine like terms: 8 + -8 = 0 0 + 4r = 16 + -8 4r = 16 + -8

Combine like terms: 16 + -8 = 8 4r = 8

Divide each side by '4'. r = 2

Simplifying r = 2

Hope that helps! ^^
