What is a correct first step in solving the inequality -4(3 - 5x) ≥ -6x + 9?
-12 - 20x ≤ -6x + 9
-12 - 20x ≥ -6x + 9
-12 + 20x ≤ -6x + 9
-12 + 20x ≥ -6x + 9
Solution:
The given inequality is
-4(3 - 5x) ≥ -6x + 9
Using the multiplicative distributive property
-12 + 20x ≥ -6x + 9
By rearranging the variables and constants
20x + 6x ≥ 9 + 12
By adding on both sides
26x ≥ 21
Dividing both sides by 26
26x/26 ≥ 21/26
x ≥ 21/26
Therefore, the correct first step is -12 + 20x ≥ -6x + 9.
What is a correct first step in solving the inequality -4(3 - 5x) ≥ -6x + 9?
Summary:
The correct first step in solving the inequality -4(3 - 5x) ≥ -6x + 9 is -12 + 20x ≥ -6x + 9.
