7x – 2y = 8Which equation is equivalent to it?

Sagot :

You have the following equation:

7x - 2y = 8

In order to find an equivalent expression, you proceed as follow:

7x - 2y = 8 subtract 7x both sides

-2y = 8 - 7x divide both sides by -2

y = 8/(-2) - 7x/(-2)

y = -4 + (7/2)x

y = (7/2)x - 4

Hence, the equivalent equation is the line y = (7/2)x - 4
