First step is expand by using distributive property
<span>2(x + 7) + 3x = 12
step 1:
2x + 14 + 3x = 12</span>
14?
17-12=5
5x2=10
10+4 =14
The answer is B because 5 times x is 5x and 5 times 6 is 30. Since there is a subtraction sign, it would be equal to 5x-30
Answer:

Step-by-step explanation:
5/2.5 = X/2
To solve a proportion, use the following equation:
(numerator * opposite denominator) = (numerator * opposite denominator)
Substitute in given numbers
(5 * 2) = (X * 2.5)
Multiply to simplify
10 = 2.5X
Divide both sides of this equation by 2.5

Hope this helps :)
