I don't understand how to solve this problem... help?
5r-(2r+8)=16
5r-(2r+8)=16
Combine like terms.
3r - 8 = 16
Add 8 to both sides.
3r = 24
r = 8
5r-(2r+8)=16
Distribute the negative~
5r-2r-8=16
Add like terms~
3r-8=16
Add 8 to each side (opposite operation)~
3r-8+8=16+8
3r=24
/3 on each side (again, opposite operation)~
r=9
PPPSSSHHH oops I ment 9...
I accidentally had 9 in my head -_-
NOOOO I ment 8!!!!!
im so sorry!
To solve this problem, we need to simplify the equation and isolate the variable r.
Step 1: Distribute the 5 to the terms inside the parentheses:
5r - (2r + 8) = 16
5r - 2r - 8 = 16
Step 2: Combine like terms on the left side of the equation:
(5r - 2r) - 8 = 16
3r - 8 = 16
Step 3: Move the constant term (-8) to the right side of the equation by adding 8 to both sides:
3r - 8 + 8 = 16 + 8
3r = 24
Step 4: Divide both sides of the equation by the coefficient of r, which is 3:
3r / 3 = 24 / 3
r = 8
So, the solution to the equation is r = 8.
