Answer:

x=10

Step-by-step explanation:

[tex]-x+ 3 = - 3x + 23\\2x+3=23 \\2x=20\\x=10[/tex]

1. Subtract -3x from both sides of equation

2. Subtract 3 from both sides of equation

3. Divide both sides by 2
1.regroup terms: 3-x=-3x+23
2. subtract 3 from both sides: -x=-3x+23-3
3. simplify -3x+23-3 to -3x+20: -x=-3+20
4. add 3x to both sides: -x+3x=20
5. simplify 3x=20 to 2x: 2x=20
6. divide both sides by 2: x=20/2
7. simplify: x=10
ANSWER: x=10
