Answer:
2. Open the bracket
Step-by-step explanation:
1. Given:
[tex]3(x + 2) = 12[/tex]
2. Open the bracket, by multiplying 3 on every term in the bracket.
[tex] (3 \times x) + (3 \times 2) = 12 \\ 3x + 6 = 12[/tex]
3.Subtraction Property of equality:
[tex]3x + 6 - 6 = 12 - 6[/tex]
4. Simplify:
[tex]3x = 6[/tex]
5. Divide property of equality:
[tex] \frac{3x}{3} = \frac{6}{3} [/tex]
6. Simplify:
[tex]x = 2[/tex]
