Here is a linear equation in two variables: y = 8x + 4

Solve the equation for x and SHOW YOUR WORK.
CORRECTI

Answer 1

Explanation:

to solve for x means to transform the equation into a form

x = ...

or

... = x

always remember to apply any change to both sides of the equation. otherwise you destroy the original equality information, and nothing makes any sense anymore.

y = 8x + 4 | subtract 4 from both sides

y - 4 = 8x | divide both sides by 8

(y - 4)/8 = x

or

y/8 - 4/8 = y/8 - 1/2 = x
