2x+1\geq 3x-3
Multiply both sides of the equation by 3. Since 3 is positive, the inequality direction remains the same.
2x+1-3x\geq -3
Subtract 3x from both sides.
-x+1\geq -3
Combine 2x and -3x to get -x.
-x\geq -3-1
Subtract 1 from both sides.
-x\geq -4
Subtract 1 from -3 to get -4.
x\leq \frac{-4}{-1}
Divide both sides by -1. Since -1 is negative, the inequality direction is changed.
x\leq 4
Fraction \frac{-4}{-1} can be simplified to 4 by removing the negative sign from both the numerator and the denominator.
