In The Equation Below, Solve For The Value Of $y$:$\frac{3}{2} Y + 5 = Y$
In the equation , we are tasked with solving for the value of . This equation is a linear equation, which means it can be solved using basic algebraic techniques.
Understanding the Equation
The given equation is . To solve for , we need to isolate the variable on one side of the equation. The equation consists of two terms: and . The goal is to get rid of the fraction and combine like terms.
Step 1: Subtract from both sides
To eliminate the fraction, we can multiply both sides of the equation by the denominator of the fraction, which is . This will get rid of the fraction and allow us to work with whole numbers.
\frac{3}{2} y + 5 = y
\implies 2 \times \left(\frac{3}{2} y + 5\right) = 2 \times y
\implies 3y + 10 = 2y
Step 2: Subtract from both sides
Now that we have eliminated the fraction, we can focus on isolating the variable . We can do this by subtracting from both sides of the equation.
3y + 10 = 2y
\implies 3y - 2y + 10 = 2y - 2y
\implies y + 10 = 0
Step 3: Subtract 10 from both sides
We are getting close to solving for . To isolate the variable, we can subtract 10 from both sides of the equation.
y + 10 = 0
\implies y + 10 - 10 = 0 - 10
\implies y = -10
Conclusion
In the equation , we have successfully solved for the value of . By following the steps outlined above, we have isolated the variable and found that .
