Answer:
x= 7
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+3)-(20)=0
STEP
1
:
Equation at the end of step 1
2 • (x + 3) - 20 = 0
STEP
2
:
STEP
3
:
Pulling out like terms
3.1 Pull out like factors :
2x - 14 = 2 • (x - 7)
Equation at the end of step
3
:
2 • (x - 7) = 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-7 = 0
Add 7 to both sides of the equation :
x = 7
