Answer:
B
Step-by-step explanation:
Given the 2 equations
y = 2x - 3 → (1)
y - 9 = - x → (2)
Substitute y = 2x - 3 into (2)
2x - 3 - 9 = - x
2x - 12 = - x ( add x to both sides )
3x - 12 = 0 ( add 12 to both sides )
3x = 12 ( divide both sides by 3 )
x = 4
Substitute x = 4 into either of the 2 equations and evaluate for y
Substituting into (1)
y = 2(4) - 3 = 8 - 3 = 5
Solution is (4, 5 ) → B
