Answer:
x = 10
Explanation:
2.1 Adding a fraction to a whole
Rewrite the whole as a fraction using 10 as the denominator :
7x 7x • 10
7x = —— = ———————
1 10
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
7x • 10 + 1 70x + 1
——————————— = ———————
10 10
Final result :
70x + 1
———————
10
