Solution - Linear equations with one unknown
u=-7
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 :
-3*(-u-1)-(-4+2*u)=0
Step by step solution :
Step 1 :
Step 2 :
Pulling out like terms :
2.1 Pull out like factors :
-u - 1 = -1 • (u + 1)
Equation at the end of step 2 :
(0 - -3 • (u + 1)) - (2u - 4) = 0
Step 3 :
Equation at the end of step 3 :
u + 7 = 0
Step 4 :
Solving a Single Variable Equation :
4.1 Solve : u+7 = 0
Subtract 7 from both sides of the equation :
u = -7
One solution was found :
u = -7How did we do?
