Answer:
<em>x=</em><em>-</em><em>1</em><em>3</em>
Step-by-step explanation:
21-3.5x+14=7-7.5x-24
21+14-3.5x=7-24-7.5x
35-3.5x=-17-7.5x
35+17=3.5x-7.5x
<u>5</u><u>2</u>=<u>-4x</u>
-4. -4
x=-13
Answer:
7
Step-by-step explanation:
Recall that, an absolute value expression is a piece-wise in effect, thus we'd check the single-sided limits,
4(5x-20)=-20
20x-80=-20
20x=60
x=3
