Answer:

r = 1

Step-by-step explanation:

Step 1: Write equation

-3r + 18 = 15r

Step 2: Solve for <em>r</em>

  1. Add 3r to both sides: 18 = 18r
  2. Divide both sides by 18: 1 = r
  3. Rewrite: r = 1

Step 3: Check

<em>Plug in r to verify it's a solution.</em>

-3(1) + 18 = 15(1)

-3 + 18 = 15

15 = 15

Step-by-step explanation:

- 3r - 15r = -18 .... Moved variables to one side and constants to the other

- 18r = - 18 ..... Simplified

r = 1 ..... Divided to isolate the r

Check:

Plug in 1 for r

-3(1) +18 = 15(1)

- 3+18 = 15

15 = 15 .... Therefore 1 is correct

Answer is 1

Hope this helps!
