Answer:
x = 7 and y = 5
Step-by-step explanation:
If we called the first number is x and the second number is y, we are given that:
x + y = 12 (1)
x = y +2 (2)
If we change (2) into (1), we would get:
y + 2 + y = 12
2y + 2 = 12
2y + 2 - 2 = 12 - 2
2y = 10
y = 5
Because y = 5 and x = y +2
so x would equal :
x = 5 + 2
x = 7
So x = 7 and y = 5
Hope this helped :3
Answer:
x = 7, y = 5.
Step-by-step explanation:
x + y = 12
x - y = 2
Adding:
2x = 14
x = 7.
Substitute x = 7 in the first equation:
y + y = 12
y = 12 - 7
y = 5.
Check that these roots are correct in the second equation:
x - y = 2
7 - 5 = 2 so correct.
