How do you solve for y in #7x + 2y = 5#?

#y = (5-7x)/2#

Or # y = -7/2x +2 1/2#

Explanation:

Seeing that there is only one equation with both x and y, it is not possible to solve for a single value for y. There are infinitely many solutions to this equation as it is. (0,2.5) (1,-1) (2,-4.5) (-1, +6) are but a few...

We can therefore only solve for y "IN TERMS OF" x.

#2y = 5-7x#

#y = (5-7x)/2#
