You can
put this solution on YOUR website!
your equation is:
2x < 3y + 6
You want to solve for y so you can graph this equation.
first get all the y terms on the left side of the equation and everything else on the right side of the equation.
you do this in the following manner:
subtract 3y from both sides of the equation to get:
-3y + 2x < 6
subtract 2x from both sides of the equation to get:
-3y < -2x + 6
multiply both sides of the equation by -1 to get:
3y > 2x - 6
notice that the inequality is reversed when you multiply both sides of this equation by -1.
divide both sides of this equation by 3 to get:
y > (2/3)x - 2
graph the equality equation of y = (2/3)x - 2 to get:
y will be any value above that line.
for example, when x = 3, any value of y > 0 will satisfy the equation.
to confirm, let x = 3 in your original equation.
your original equation is:
2x < 3y + 6
when x is equal to 3, this becomes:
6 < 3y + 6
subtract 6 from both sides of this equation to get:
0 < 3y
divide both sides of this equation by 3 to get:
0 < y
since 0 < y is the same as y > 0, the solution is confirmed.
