Q. Solve for x.Your answer must be simplified.−30<−4x
Multiply by −4: We are given the inequality -30 < \frac{x}{-4}. To solve for x, we need to isolate x on one side of the inequality. To do this, we will multiply both sides of the inequality by −4. Remember that when we multiply or divide both sides of an inequality by a negative number, we must reverse the direction of the inequality sign.Calculation: -30 \times (-4) > x (Note the inequality sign has been reversed)−30×(−4)=120So, we have 120 > x
Calculate: We have found that 120 > x, which can also be written as x < 120. This means that x must be less than 120.
