2r + 9 = 7 - 3r

Subtract 9 from each side:

2r = -2 - 3r

Add 3r to each side:

5r = -2

Divide both sides by 5:

r - -2/5

Which of the following inequalities is equivalent to 3-(w+2)>4+2w

Kay [80]

$3 - w - 2 > 4 + 2w \\ - w - 2w > 4 + 2 - 3 \\ - 3w > 6 - 3 \\ \frac{ - 3w}{ - 3} > \frac{3}{ - 3} \\ w < - 1$
The sign at the end changes because both sides of the equation are being divided by a negative number.
