Answer:
(2, -3)
Step-by-step explanation:
Apparently, the equations are supposed to be ...
The solution for x can be found by subtracting the second equation from the first:
(4x +y) -(3x +y) = (5) -(3)
x = 2 . . . . . . . matches the second answer choice
Y can be found from either equation:
y = 5 - 4x . . . . . subtract 4x from the first equation
y = 5 -4(2) = -3
The solution is (x, y) = (2, -3).
Answer:
Step-by-step explanation:
Answer and Step-by-step explanation:
The mistake is that the sign (<) isn't flipped.
When a negative number is multiplied, the sign of the inequality flips to go the other way, so < would go >.
7 + 6 = 13
13 - 6 = 7 or 13 - 7 = 6
