Final answer:
To calculate the equation 5x+7y=6, you can solve for y in terms of x by isolating y and dividing by its coefficient. You need a second linear equation to find specific numerical values for x and y.
Step-by-step explanation:
To calculate an equation like 5x+7y=6, you need another equation that involves the variables x and y to solve for specific values. Without a second equation, you can solve for one variable in terms of the other.
Example
Here's how you can express y in terms of x using the original equation:
- Subtract 5x from both sides of the equation to isolate the term with y:
7y = 6 - 5x. - Divide both sides by 7 to solve for y:
y = (6 - 5x) / 7.
Now you have expressed y in terms of x, but to find specific numerical solutions for x and y, a second linear equation would be necessary to create a system of equations.
