I hope this helped! If so, please mark brainliest!
Step by step solution :
Step 1 :
Pulling out like terms :
1.1 Pull out like factors :
2e + 4 = 2 • (e + 2)
Equation at the end of step 1 :
Step 2 :
Equations which are never true :
2.1 Solve : 2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
2.2 Solve : e+2 = 0
Subtract 2 from both sides of the equation :
e = -2
Answer: -2
Step-by-step explanation:
Given :
9e - 7 = 7e - 11
Add 7 to both sides , we have
9e = 7e - 11 + 7
9e = 7e - 4
subtract 7e from both sides
9e - 7e = -4
2e = -4
divide through by 2
e = -2
