which number is a solution to 3x - 19 > 5x - 7 or 6x -27 >
30 + 3x
The answer is one of the following:
a. -19
b. -5
c. 5
d. 19
Solution
In an inequality adding or removing the same expression to
both sides of the inequality leads to an equivalent
inequality.
3x - 19 > 5x - 7is equivalent to 3x - 19 + (- 3x + 7) > 5x - 7
+ (- 3x + 7),
simplified to -12 > 2x, equivalent to x < -6
6x -27 > 30 + 3x is equivalent to6x -27 + (-3x +27)> 30 +
3x+ (-3x +27)
simplified to 3x > 57 , equivalent to x > 19
