Answer:
The answer will be 7(2x - 1)
Step-by-step explanation:
1) Convert 7 and 1/2 to improper fraction. Use this rule: a b/c = ac + b/c
[tex]7x + \frac{1}{2} + 7x - \frac{7 \times 2 + 1}{2} [/tex]
2) Simplify 7 × 2 to 14 .
[tex]7x + \frac{1}{2} + 7x - \frac{14 + 1}{2} [/tex]
3) Simplify 14 + 1 to 15.
[tex]7x + \frac{1}{2} + 7x - \frac{15}{2} [/tex]
4) Collect like terms.
[tex](7x + 7x) + ( \frac{1}{2} - \frac{15}{2} )[/tex]
5) simplify.
[tex]14x - 7[/tex]
6) Factor out the common term 7.
[tex]7(2x - 1)[/tex]
Therefor, the answer is 7( 2x - 1 ).
