1. Isolating the variable
Isolating the variable is an important step in fixing for y. It includes shifting all phrases containing y to at least one facet of the equation and all different phrases to the opposite facet. This simplifies the equation and makes it simpler to resolve for y.
To isolate the variable, we are able to use the next steps:
- Determine the time period with y.
- Add or subtract the identical worth to each side of the equation to maneuver the time period with y to at least one facet.
- Simplify each side of the equation.
For instance, let’s take into account the equation 2y + 5 = 11. To isolate the variable, we are able to subtract 5 from each side:
2y + 5 – 5 = 11 – 5
2y = 6
Now, we are able to divide each side by 2 to resolve for y:
2y / 2 = 6 / 2
y = 3
Isolating the variable is an important step in fixing for y as a result of it permits us to simplify the equation and deal with the variable we try to resolve for. By isolating the variable, we are able to extra simply apply algebraic operations to resolve for y.
2. Simplifying the equation
Simplifying the equation is an important step in fixing for y as a result of it permits us to isolate the variable and resolve for its worth. By simplifying the equation, we take away any pointless phrases or operations that make it harder to resolve for y.
To simplify the equation, we are able to use a wide range of algebraic operations, akin to:
- Combining like phrases
- Increasing and factoring
- Utilizing the distributive property
- Utilizing the order of operations
For instance, let’s take into account the equation 2y + 5 = 11. To simplify the equation, we are able to subtract 5 from each side:
2y + 5 – 5 = 11 – 5
2y = 6
Now, we are able to divide each side by 2 to resolve for y:
2y / 2 = 6 / 2
y = 3
Simplifying the equation is an important step in fixing for y as a result of it permits us to deal with the variable we try to resolve for and to use algebraic operations to search out its worth.
