Purchase this Solution
Solution Summary

This shows how to solve for y in a linear equation.

Solution Preview

2x - 5y = -1
Adding 5y to both sides of the equation gives:
2x - 5y + 5y = 5y - 1
Now -5y + 5y on the left hand side of the equation is equal to zero therefore the equation becomes:
2x = 5y - ...
