Answer:
Explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
63-(9*j)=0
Step by step solution :
STEP

:
Pulling out like terms
1.1 Pull out like factors :
63 - 9j = -9 • (j - 7)

Equations which are never true:
2.1 Solve : -9 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
2.2 Solve : j-7 = 0
Add 7 to both sides of the equation :
j = 7
solved
j = 7
