Solution - Linear equations with one unknown
j=1
Step by Step Solution
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-7*j-14*j+9-(-12)=0
Step by step solution :
Step 1 :
Pulling out like terms :
1.1 Pull out like factors :
-21j + 21 = -21 • (j - 1)
Equation at the end of step 1 :
Step 2 :
Equations which are never true :
2.1 Solve : -21 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
2.2 Solve : j-1 = 0
Add 1 to both sides of the equation :
j = 1
One solution was found :
j = 1How did we do?
