Q:

5/8(x-1/3)=5/12 can someone help me figure out what x is?

Accepted Solution

A:
Solve for x:(5 (x - 1/3))/(8) = 5/12
Put each term in x - 1/3 over the common denominator 3: x - 1/3 = (3 x)/3 - 1/3:(5 (3 x)/3 - 1/3)/(8) = 5/12
(3 x)/3 - 1/3 = (3 x - 1)/3:(5 (3 x - 1)/3)/(8) = 5/12
3Γ—8 = 24:(5 (3 x - 1))/24 = 5/12
Multiply both sides of (5 (3 x - 1))/24 = 5/12 by 24/5:(24Γ—5 (3 x - 1))/(5Γ—24) = (24Γ—5)/(5Γ—12)
(24Γ—5)/(5Γ—12) = (24Γ—5)/(5Γ—12):(24Γ—5 (3 x - 1))/(5Γ—24) = (24Γ—5)/(5Γ—12)
(24Γ—5 (3 x - 1))/(5Γ—24) = (5Γ—24)/(5Γ—24)Γ—(3 x - 1) = 3 x - 1:3 x - 1 = (24Γ—5)/(5Γ—12)
(24Γ—5)/(5Γ—12) = 5/5Γ—24/12 = 24/12:3 x - 1 = 24/12
The gcd of 24 and 12 is 12, so 24/12 = (12Γ—2)/(12Γ—1) = 12/12Γ—2 = 2:3 x - 1 = 2
Add 1 to both sides:3 x + (1 - 1) = 1 + 2
1 - 1 = 0:3 x = 2 + 1
2 + 1 = 3:3 x = 3
Divide both sides of 3 x = 3 by 3:(3 x)/3 = 3/3
3/3 = 1:x = 3/3
3/3 = 1:Answer:Β  x = 1
