2(3x - 2) > 22
Expand (eliminate parentheses on) the left side:
6x - 4 > 22
Add 4 to each side:
6x > 26
Divide each side by 6 :
x > 13/3

The solution to the inequality 2 ( 3 x − 2 ) ≥ 22 is x ≥ 4 3 1 ​ . This can also be expressed as x ∈ [ 4 3 1 ​ , ∞ ) .

[tex] - 3 \times (90 \div 15) \\ = - 3 \times 6 \\ = - 18[/tex]
