Answer:
x=4
Step-by-step explanation:
1+2x=-7+4x
-2x -2x
you subtract both sides with two
1=-7+2x
+7+7
you add 7 both sides of the equation
8=2x
now you divide 8 and 2
x=4
Answer: x=4
Step-by-step explanation:
First add 7 to both sides of the equation.
1 +2x = -7 +4x
1 +2x (+7) = -7 +4x (+7)
8 +2x = 4x
Then subtract 2x from both sides of the equation.
8 +2x = 4x
8 +2x (-2x) = 4x (-2x)
8 = 2x
Last divide both sides of the equation by 2 to isolate the variable (x).
8 = 2x
8/2 =2x/2
4 = x
