What is the solution to the system below?
y = 5x - 9
y = x + 3
2 answers:
Answer:
I think it like this .........
Answer:
(3, 6 )
Step-by-step explanation:
Given the 2 equations
y = 5x - 9 → (1)
y = x + 3 → (2)
Substitute y = 5x - 9 into (2)
5x - 9 = x + 3 ( subtract x from both sides )
4x - 9 = 3 ( add 9 to both sides )
4x = 12 ( divide both sides by 4 )
x = 3
Substitute x = 3 into either of the 2 equations and evaluate for y
Substituting into (2)
y = 3 + 3 = 6
solution is (3, 6 )
