Answer:
r = (-3)/32
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
