Step-by-step explanation:
Answer:
5
Step-by-step explanation:
its 45
–2x + 4y = –7 . . . . . (1)
y = -1/2x + 5 . . . . . . (2)
Putting (2) into (1), we have:
-2x + 4(-1/2x + 5) = -7
-2x - 2x + 5 = -7
-4x = -7 - 5 = -12
x = -12/-4 = 3
y = -1/2(3) + 5 = -3/2 + 5 = 7/2
Hence, the system has one solution.
I don't know if it's 74, but I got -80. here's how:
(3x + 5 x -4x + 7) (-4)
(8 x -4x + 7) (-4)
(8 x 3) (-4)
24 x -4 = -80
A ur welcome :D hope im helping:D
