Part 1/
5 + x - 14 = x - 7
We’ll cancel (X) from both sides;
5 - 14 = -7
-9 = -7
Since, -9 = -7 is False, there is no solution.

Part2/
If we use x = -2, 0, 3
1) Case of X = -2
5 + (-2) - 14 = (-2) - 7
5 - 2 - 14 = -2 - 7
3 - 14 = -9
-11 = -9 .... False / No Solution
2) Case of X = 0
5 + (0) - 14 = (0) - 7
5 - 14 = -7
-9 = -7 ... False / No Solution
3) Case of X = 3
5 + (3) - 14 = (3) - 7
8 - 14 = -4
-6 = -4 ... False / No Solution
Measure the amount of certain radioactive elements in the rock when rocks are formed, small amounts of radioactive elements usually get included as the rock ages, more and more of the uranium changes into lead.
My dad if this doesn’t help
