Hello there!
x + 2y = 5
y = x + 1
We gonna solve y = x + 1 for y
Let's start solving the equation by substitute x + 1 for y in x + 2y = 5
x + 2y = 5 (we gonna replace y by x +1)
x + 2( x + 1) = 5
x + 2x + 2 = 5
3x + 2 = 5
3x = 5 - 2
3x = 3
x = 3/3
x = 1
Since we have the value for x, it will be easier for us to find y. In order to find y we just need to replace x by its value which is 1. So let's go!
We have y = x + 1 >> so we gonna substitute 1 for x
y = x + 1
y= 1+1
y=2
see.... easy :)
The final answer is: (1,2)
The correct option is A (Yes)
