Answer:
16
Explanation:
"sum" means the number you get after adding two or more numbers together, in this case 4 and an unknown, and the sum is given: 20.
Use this information to find the answer.
20-4=16
The values of x = 4.
Considering the number x, from the data we can write:
Based on the given conditions, formulate
4 x + 4 = 20
Rearrange variables to the left side of the equation:
4 x = 20 - 4
4 x = 16
Divide both sides of the equation by the coefficient of the variable:
x = 16 / 4
Cross out the common factor:
x = 4.
Therefore, the correct values of x = 4.
