Answer:

r = 3 or r = -6

Step-by-step explanation:

Solve for r over the real numbers:

(r - 3) (r + 6) = 0

Split into two equations:

r - 3 = 0 or r + 6 = 0

Add 3 to both sides:

r = 3 or r + 6 = 0

Subtract 6 from both sides:

Answer: r = 3 or r = -6

Solve for x <br> - 3 (x - 4) = 2x + 4x + 5

In-s [12.5K]

Answer:

$x=\frac{7}{9}$

Step-by-step explanation:

-3(x-4)=2x+4x+5

distribute -3 into (x-4)

-3x+12=2x+4x+5

combine like terms

-3x+12=6x+5

subtract 6x on both sides

-3x-6x+12=5

combine like terms again

-9x+12=5

subtract 12 on both sides

-9x=-7

divide both sides with -9

$\frac{-9x}{-9} \frac{-7}{-9}$

x= $\frac{7}{9\\}$

hope this helps
