Question

Find number x, if when you add 7 to it and double the result you get 19 more than x.

NEED HELP ASAP

Answer 1

x = 5.

Explanation:

We can set up equivalent equations like this to solve:

2(x + 7) = x + 19

Distribute the 2, giving us:

2x + 14 = x+ 19

Move the variables to one side, and the numbers to the other, giving us:

x = 5
