Answer:
8 = 2x + 4
collect like terms
8 - 4 = 2x
4 = 2x
divide both sides by 2
4/2 = 2x/2
X = 2
Answer:
x=2 (answer should have a positive sign.)
Step-by-step explanation:
To solve this problem, you have to isolate the x from one side of the equation.
First, switch sides.
8=2x+4
2x+4=8
Subtract by 4 from both sides.
2x+4-4=8-4
Solve.
8-4=4
2x=4
Then, divide by 2 from both sides.
2x/2=4/2
Solve.
4/2=2
x=2
The solution is 2.
