Answer:
x = 1, y = 3
Step-by-step explanation:
Given the 2 equations
y = 2x + 1 → (1)
y = - x + 4 → (2)
Substitute y = 2x + 1 into (2)
2x + 1 = - x + 4 ( add x to both sides )
3x + 1 = 4 ( subtract 1 from both sides )
3x = 3 ( divide both sides by 3 )
x = 1
Substitute x = 1 into (1) and evaluate for y
y = 2(1) + 1 = 2 + 1 = 3
Then solution is x = 1, y = 3
