Question

Solve for r.

-7.61 - 4.3r = -8.1r - 3.81

Answer 1

r=1

Explanation:

-7.61 - 4.3r = -8.1r - 3.81

(bring like terms to one side)

-4.3 r = -8.1r -3.81 + 7.61

-4.3r + 8.1 r =-3.81 + 7.61

(consolodate)

3.8r = 3.8

(divide right by # of r)

r = 3.8/3.8

r = 1

Answer 2

r = 1

Explanation:

-7.61 - 4.3r = -8.1r - 3.81

-7.61 = -3.8r - 3.81

-3.8 = -3.8r

r = 1
