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
