Question

Which shows the solution to the
inequality? 6(x - 2) +21 < 39
A x < 5
C x>3
B X >5
D x < 3

Answer 1

Answer:

A

Step-by-step explanation:

multiply the 6 with the numbers in the bracket

6x -12 + 21 < 39

addition(-12+21 =9)

6x + 9 < 39

grouping

6x < 39-9

6x < 30

divide both sides by the coefficient of x

6x/6 < 30/6

x < 5
