Answer:
B
Step-by-step explanation:
Given the 2 equations
y = 3x + 4 → (1)
y = 6x + 10 → (2)
Substitute y = 6x + 10 into (1)
6x + 10 = 3x + 4 ( subtract 3x from both sides )
3x + 10 = 4 ( subtract 10 from both sides )
3x = - 6 ( divide both sides by 3 )
x = - 2
substitute x = - 2 into either of the 2 equations and evaluate for y
Substituting into (1)
y = 3(- 2) + 4 = - 6 + 4 = - 2
solution is (- 2, - 2 ) → B
