3x+y=7 for y -x+y=13 for y f=5gh for h

y=7-3x

y=13+x

h=f/5g

thank you

To solve the equation 3x + y = 7 for y, we need to isolate y on one side of the equation. Here's how you can do it:

1. Start with the equation: 3x + y = 7.
2. To isolate y, we need to move the term with x to the other side of the equation.
Subtract 3x from both sides: y = 7 - 3x.

The equation -x + y = 13 can be solved in a similar manner:

1. Begin with the equation: -x + y = 13.
2. To isolate y, we'll move the term with x to the other side of the equation.
Add x to both sides: y = 13 + x.

Now, let's solve the equation f = 5gh for h:

1. Start with the equation: f = 5gh.
2. To solve for h, we need to isolate it on one side of the equation.
Divide both sides of the equation by 5g: h = f / (5g).

By following these steps, you can solve linear equations and expressions for the variable you are interested in.
