Step-by-step explanation:
x + y=6
x= y + 2
Substitute the second equation into the first
x+y = 6
(y+2) +y =6
Combine like terms
2y+2 = 6
Subtract 2
2y+2-2 = 6-2
2y = 4
Divide by 2
2y/2 = 4/2
y =2
Now find x
x = y+2
x = 2+2
x=4

Ответ:
x + y=6 1
x= y + 2 2
Substitute x= y + 2 into x + y=6
y + y + 2 = 6
2y = 6 - 2
2y = 4
Divide both sides by 2
y = 2
Substitute y = 2 into x + y=6
x + 2 = 6
x = 6 - 2
x = 4
y = 2 x = 4
hope this helps.
