What is the answer for - 3 (1+6r) = 14r

r = (-3) / 32

Step-by-step explanation:

Solve for r:

-3 (6 r + 1) = 14 r

Expand out terms of the left hand side:

-18 r - 3 = 14 r

Subtract 14 r from both sides:

(-18 r - 14 r) - 3 = 14 r - 14 r

-18 r - 14 r = - 32 r:

-32 r - 3 = 14 r - 14 r

14 r - 14 r = 0:

-32 r - 3 = 0

Add 3 to both sides:

(3 - 3) - 32 r = 3

3 - 3 = 0:

-32 r = 3

Divide both sides of - 32 r = 3 by - 32:

(-32 r) / (-32) = 3 / (-32)

(-32) / (-32) = 1:

r = 3 / (-32)

Multiply numerator and denominator of 3 / (-32) by - 1:

Answer: r = (-3) / 32
