Answer:
(- 7, - 4 )
Step-by-step explanation:
Given the 2 equations
y = 3x + 17 → (1)
y = 4x + 24 → (2)
Since both equations express y in terms of x , equate the right sides
4x + 24 = 3x + 17 ( subtract 3x from both sides )
x + 24 = 17 ( subtract 24 from both sides )
x = - 7
Substitute x = - 7 into either of the 2 equations and solve for y
Substituting x = - 7 in (1)
y = 3(- 7) + 17 = - 21 + 17 = - 4
Solution is (- 7, - 4 )
Answer:
Step-by-step explanation:
y = 3x + 17..........(1)
y = 4x + 24.........(2)
Substituting (2) into (1)
4x + 24 = 3x + 17
4x - 3x = 17 - 24
x = - 7
And y = 3x + 17
y = 3(-7) +17
y = -21 + 17
y = -4
