Question

(ii) -x + 24 =-3x - 20​

Answer 1

-x + 24= -3x -20

-x+ 3x= -20 - 24

2x= -44

x= -22

Answer 2

Regroup terms.

24-x=-3x-20

24−x=−3x−20

2 Add 3x3x to both sides.

24-x+3x=-20

24−x+3x=−20

3 Simplify  24-x+3x24−x+3x  to  24+2x24+2x.

24+2x=-20

24+2x=−20

4 Subtract 2424 from both sides.

2x=-20-24

2x=−20−24

5 Simplify  -20-24−20−24  to  -44−44.

2x=-44

2x=−44

6 Divide both sides by 22.

x=− 44/2

x=−22

so the answer is x=−22
