Answer:
got what?
Step-by-step explanation:
twice a number: 2x
is 27 more than half the number: 1/2x
2x = 1/2x + 27
Isolate the x. Subtract 1/2x from both sides
2x (-1/2x) = 1/2x (-1/2x) + 27
2x - 1/2x = 27
1.5x = 27
Isolate the x. Divide 1.5 from both sides
1.5x/1.5 = 27/1.5
x = 27/1.5
x = 18
18 is the number
hope this helps
