Answer:
x = 12
Step-by-step explanation:
First of all, what you will want to do is plug in your y into the first equation, to find the x.
y = x - 5 ----> 7 = x - 5
Next, think about your possible solutions here.... Flip the equation:
5 + 7 = ? ---> 5 + 7 = 12
Now, plug both your x and y in the original equation:
7 = 12 - 5 Does this match?
7 = 7 Yes!
This is the simplest way I can explain it! I hope it is understandable, correct, and helpful. Have a great day :D
