Answer:
x = -4/5
Step-by-step explanation:
4x + 12 = 8 – x
4x + 4 = -x
4 = -5x
x = 4 / -5
x = -4/5
Answer:
x = 5
Step-by-step explanation:
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
4*x-12-(8)=0
Step by step solution :
Step 1 :
Pulling out like terms :
1.1 Pull out like factors :
4x - 20 = 4 • (x - 5)
Equation at the end of step 1 :
Step 2 :
Equations which are never true :
2.1 Solve : 4 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
2.2 Solve : x-5 = 0
Add 5 to both sides of the equation :
x = 5
