Anthony Wagner · Answer 1

Rearrange ➡ 3 + 9 * (1 - 5r) - (25)

Step 1. Equation ⬇

(3+9 * (1 - 5r)) : - 25 = 0

Step 2. Take out the like terms (factors) ⬇

-45r - 13 = - 1 * (45 + 13)

Equation part 2 ➡ - 45 - 13 = 0

Add 13 to both sides of the equation ➡ - 45=13

Multiply both sides of the equation by (-1) : 45r = - 13

divide both sides of the equation by 45

r = - 0.289
