Solve the following simultaneous equations. x + y = 3
x -y = 1
2 answers:
Answer: x = 2, y = 1
Step-by-Step Solution:
=> x + y = 3 (Eq. 1)
=> x - y = 1 (Eq. 2)
Adding Eq. 1 and Eq. 2, we get :-
2x = 3 + 1
2x = 4
x = 4/2
=> x = 2
Therefore, x = 2
Substitute value of ‘x’ in Eq. 1 :-
x + y = 3
(2) + y = 3
2 + y = 3
y = 3 - 2
=> y = 1
Therefore, y = 1
Hence, x = 2 and y = 1.
Answer:
<u>x = 2, y = 1 or (2, 1)</u>
Step-by-step explanation:
<u>Solving by elimination method</u> :
- x + y + (x - y) = 3 + 1
- 2x = 4
- x = 2
The solution is : x = 2, y = 1 or (2, 1)

Answer:
y + 1 = 4 (x + 3)
Step-by-step explanation:
The formula is y - y1 = m (x - x1), so you put the variables in to y1 and x1 plus add the slope in as m, and there you are! Point slope form.
