Answer:
- x = 3
- y = 1
Step-by-step explanation:
I am going to guess these are simultaneous equations but the question is unclear.
- y = 4-x
- y = x - 2
- re arrange
- x + y = 4
- -x + y = -2
- We can cancel out x to solve for y
- 2y = 2
- y = 1
- now solve for x
- x + y = 4
- x + 1 = 4
- x = 3
- now verify solutions
- -x + y = -2
- -3 + 1 = -2
- -2 = -2
Answer:
x = 3 , y = 1
Step-by-step explanation:
given the system of equations
y = 4 - x → (1)
y = x - 2 → (2)
substitute y = x - 2 into (1)
x - 2 = 4 - x ( add x to both sides )
2x - 2 = 4 ( add 2 to both sides )
2x = 6 ( divide both sides by 2 )
x = 3
substitute x = 3 into either of the 2 equations and solve for y
substituting into (1)
y = 4 - 3 = 1
The solution is x = 3 , y = 1
