Answer:
1. Distributive Property
2. Addition Property of Equality
3. Multiplicative Property of Equality
Step-by-step explanation:
1. The 3 is multiplied by each number in the parenthesis
3*10=30
3*2=6
So 3*(10-2x)=30-6x
2. The 30 is subtracted from both sides
30-6x-30 = -6x
6-30 = -24
30-6x-30=6-30
So -6x=-24
3. The -6 is divided from both sides
-6x/-6 = x
-24/-6 = 4
-6x/-6 = -24/-6
So x=4
For the denominators (7, 13) the least common multiple (LCM<span>) is </span>91.
Therefore, the least common denominator (LCD<span>) is </span>91.
<span>Rewriting the original inputs as equivalent fractions with the </span>LCD:
<span>78/91, 49/91.</span>
