Solution - Linear equations with one unknown
v=-10
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 :
-9*(-v-10)-(-10-v)=0
Step by step solution :
Step 1 :
Step 2 :
Pulling out like terms :
2.1 Pull out like factors :
-v - 10 = -1 • (v + 10)
Equation at the end of step 2 :
(0 - -9 • (v + 10)) - (-v - 10) = 0
Step 3 :
Pulling out like terms :
3.1 Pull out v+10
Note that -v-10 =(-1)• v+10
After pulling out, we are left with :
(v+10) • ( 9 * (-1) +( (-1) ))
Equation at the end of step 3 :
-10 • (v + 10) = 0
Step 4 :
Equations which are never true :
4.1 Solve : -10 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
4.2 Solve : v+10 = 0
Subtract 10 from both sides of the equation :
v = -10
One solution was found :
v = -10How did we do?
