Answer:
x = -1
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-2*(x-5)+7-(19)=0
Step by step solution
Equation at the end of step 1
((0 - 2 • (x - 5)) + 7) - 19 = 0
Pulling out like terms
3.1 Pull out like factors :
-2x - 2 = -2 • (x + 1)
Equation at the end of step
3
-2 • (x + 1) = 0
STEP
4
Equations which are never true
4.1 Solve : -2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
4.2 Solve : x+1 = 0
Subtract 1 from both sides of the equation :
x = -1
