Answer 3

Solving Equations

To solve the given equations, we'll isolate the variable on one side of the equation.

a) x - 1/4 = 3/7

To solve for x, we'll add 1/4 to both sides of the equation: ``` x - 1/4 + 1/4 = 3/7 + 1/4 x = 3/7 + 1/4 ``` Now, we'll find a common denominator for 7 and 4, which is 28. Then, we'll convert both fractions to have the common denominator: ``` x = 12/28 + 7/28 x = 19/28 ``` So, x = 19/28.

b) 1/2 - x = 3/8

To solve for x, we'll subtract 1/2 from both sides of the equation: ``` 1/2 - x - 1/2 = 3/8 - 1/2 -x = 3/8 - 1/2 ``` Now, we'll find a common denominator for 8 and 2, which is 8. Then, we'll convert both fractions to have the common denominator: ``` -x = 3/8 - 4/8 -x = -1/8 ``` Multiplying both sides by -1 to solve for x gives us: ``` x = 1/8 ``` So, x = 1/8.

c) y + 4/15 = 5/12

To solve for y, we'll subtract 4/15 from both sides of the equation: ``` y + 4/15 - 4/15 = 5/12 - 4/15 y = 5/12 - 4/15 ``` Now, we'll find a common denominator for 12 and 15, which is 60. Then, we'll convert both fractions to have the common denominator: ``` y = 25/60 - 16/60 y = 9/60 ``` Simplifying the fraction gives us: ``` y = 3/20 ``` So, y = 3/20.

These are the solutions for the given equations.
