Math Problem Statement

Solve the equation 1 2 y + 7

1 6 y 1 2 y + 7

1 6 y .

y

y

Solution

We are given the equation:

12y+7=16y\frac{1}{2}y + 7 = \frac{1}{6}y

Let's solve for yy.

Step 1: Eliminate the fractions

To eliminate the fractions, multiply both sides of the equation by 6, the least common denominator of 2 and 6:

6(12y+7)=616y6 \left(\frac{1}{2}y + 7\right) = 6 \cdot \frac{1}{6}y

Simplifying both sides:

3y+42=y3y + 42 = y

Step 2: Isolate the variable yy

Now, subtract yy from both sides to move all terms involving yy to one side:

3yy+42=03y - y + 42 = 0

Simplify:

2y+42=02y + 42 = 0

Step 3: Solve for yy

Subtract 42 from both sides:

2y=422y = -42

Now, divide both sides by 2:

y=21y = -21

Final Answer:

y=21y = -21
