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

Jul 9, 2016

$y = \frac{5 - 7 x}{2}$

Or $y = - \frac{7}{2} x + 2 \frac{1}{2}$

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.

$2 y = 5 - 7 x$

$y = \frac{5 - 7 x}{2}$
