Question

Solving literal equations
Solving for y
-x + 3y = -6

Answer 1

Since y is the variable, x is considered here as a constant.

Then :

-x + 3y = -6

we add x in both left side and right side of the equation :

-x + x + 3y = -6 + x

3y = -6 + x

Then we divide both side by three :

3y / 3 = (-6+x) /3

y = (-6+x)/3

y = -6/3 + x/3

y= -2 + x/3
