are not parents.
<span>The results showed that 150 of the adults with children and
40 of those without thought the park should be expanded. So there are 180 – 150 = 30 parents who
answered no. and 70 – 40 = 30 not parents who answered no.</span>
<span>

parents 150 | 30
not parents 40 | 30
</span>
|2x - 5| - 2 = 3 |add 2 to both sides
|2x - 5| = 5 ⇔ 2x - 5 = 5 or 2x - 5 = -5 |add 5 to both sides
2x = 10 or 2x = 0 |divide both sides by 2
x = 5 or x = 0
