Answer:
(- 3, - 5 )
Step-by-step explanation:
y = 4x + 7 → (1)
y = 8x + 19 → (2)
substitute y = 8x + 19 into (1)
8x + 19 = 4x + 7 ( subtract 4x from both sides )
4x + 19 = 7 ( subtract 19 from both sides )
4x = - 12 ( divide both sides by 4 )
x = - 3
substitute x = - 3 into either of the 2 equations and solve for y
substituting into (1)
y = 4(- 3) + 7 = - 12 + 7 = - 5
solution is (- 3, - 5 )
