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:
Number:3.75
Equation:7 x-9=3(x+2)
Step-by-step explanation:
Let the number be x.
According to the question,
7 x-9=3(x+2)
7 x-9= 3 x+ 6
7 x- 3 x= 9+6
4 x= 15
x=15/4
x=3.75
If you verify the answer you will get,
11.25=11.25
