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! ^^
