Answer:
j = 8
Explanation:
Given: The sum of j and 47 is 55 as an equation
To: Solve for j
Solution:
Sum means Addition (+)
∴ the sum of j and 47 is 55 will be written as:
j + 47 = 55
Hence, to solve for j, we subtract both sides of the equation by 47 in other to make the variable j we are solving for the subject of the formula
Thus, we get
j + 47 - 47 = 55 - 47
Therefore,
j + 0 = 8
So,
j = 8
