Answer: 22
Step-by-step:
2-4x=22
One solution was found :
x = -5
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
2-4*x-(22)=0
Step by step solution :
Step 1 :
Pulling out like terms :
1.1 Pull out like factors :
-20 - 4x = -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
Subtract 5 from both sides of the equation :
x = -5
One solution was found :
x = -5
