4 1 + w = 6 3 1 ∣ ( − 4 1 ) 4 1 − 4 1 + w = 6 3 1 − 4 1 w = 6 12 4 − 4 3 w = 6 12 1
1/4 + w = 6 1/3
1/4 - 1/4
w = 6 1/12
To solve the equation 4 1 + w = 3 19 , first subtract 4 1 from both sides to isolate w . Then find a common denominator to perform the subtraction, leading to the solution w = 12 73 or approximately 6.0833. The answer can also be expressed as a mixed number, 6 1/12.
