Question

Y=2+x
y = 3x + 5

please help

Answer 1

Hello !

1. We have :

`y=2+x\\y = 3x + 5`

2. You know that y = y so :

`2+x= 3x + 5`

3. Solve the equation

3.1 solve x

`2+x= 3x + 5\\\\2 + x - x = 3x + 5 - x\\\\2 = 2x + 5\\\\2 - 5 = 2x + 5 - 5\\\\-3 = 2x\\\\x = -3/2\\\\\boxed{x=-1,5}`

3.2 solve y

`y = 2 + x\\\\y = 2 + (-1,5)\\\\y = 2 - 1,5\\\\\boxed{y = 0,5}`

4. Conclusion

x = -3/2

y = 0,5
