Answer:
r= -2.4
Step-by-step explanation:
Simplifying
6r + 4 = r + -8
Reorder the terms:
4 + 6r = r + -8
Reorder the terms:
4 + 6r = -8 + r
Solving
4 + 6r = -8 + r
Solving for variable 'r'.
Move all terms containing r to the left, all other terms to the right.
Add '-1r' to each side of the equation.
4 + 6r + -1r = -8 + r + -1r
Combine like terms: 6r + -1r = 5r
4 + 5r = -8 + r + -1r
Combine like terms: r + -1r = 0
4 + 5r = -8 + 0
4 + 5r = -8
Add '-4' to each side of the equation.
4 + -4 + 5r = -8 + -4
Combine like terms: 4 + -4 = 0
0 + 5r = -8 + -4
5r = -8 + -4
Combine like terms: -8 + -4 = -12
5r = -12
Divide each side by '5'.
r = -2.4
Simplifying
r = -2.4
