oops I meant less than
> = greater than
< = less than
.9x + 9 < 1.3x - 6
Subtract 1.3x and 9 from both sides.
-.4x < -15
Divide by -.4, which reverses the carat.
x > 15/.4
x > 37.5
< = less than
.9x + 9 < 1.3x - 6
Subtract 1.3x and 9 from both sides.
-.4x < -15
Divide by -.4, which reverses the carat.
x > 15/.4
x > 37.5
