Question

Which ordered pairs make the inequality true?

Answer 1

1.
$(-2,3) \\ x=-2 \\ y=3 \\ \Downarrow \\ -2+3 \times 3$

The ordered pairs (-2,3) and (5,1) make the inequality true.

2.
$15y-3(4y+10)=15y-3 \times 4y-3 \times 10= 15y-12y-30= \\ =3y-30$

The simplified form of the expression is 3y-30.
