Answer:
Step-by-step explanation:
a number = x
Sum of a number and two: (x + 2)
(Sum of a number and two) is doubled: 2 * (x + 2)
The result (put an equal sign): =
Three less than the number: x - 3
Now just put The two bolded parts together and an equal sign between them.
2(x + 2) = x -3 Remove the brackets
2x + 4 = x - 3 Subtract x from each side
2x - x + 4 = x -x - 3 Combine
x + 4 = - 3 Subtract 4
x +4 - 4 = -3 - 4
x = - 7
